I see filenames are not lowererd as in debian.

Woukd it work to have a real 64 gcmd ?

Exactly, But there's a step before: What libs are needed to compile ? 
Of course they are checked by .configure / autoconf, but even on a
fast box, that needs some time and (more precious) attention to run 
through. And possibly you see any error message only at compiling.
Not to speak of slow boxes. And then you always got only one error 
after the other. All in all, what a waste of time !
I imagine to have - before any configuring or compilation - a list of
libraries  (sorted after runtime and -devel) that are necessary to compile
and run the app. That means, even without any binary (yet) for ldd.
Just as complete as any debian package dependencies would be.

There should be some make or gcc feature...i see there are some 
_LIBS in the Makefile, but that's only some, and again with weird 
naming.

How to work from that list down to packages is the second step,
probably there have to be distribution specific solutions, taking into 
account the different naming policies and differences in LSB compatibility.  
Finally, if anything else works, missing packages could be detected
and installed by just saying something like

checdep --install-missing gnome-commander

[There was a prog that monitors the runtime environment
of any process, catches any file-not-found access and tries
to install the missing packages autamtically ...it probably 
would not work for compiling, as explained above.  
I already forgot the name, too.]

ack.
You can also search other distros, like for debian,
http://www.debian.org/distrib/packages or the unofficial 
repositories on http://www.apt-get.org/search.php

I see. This is Assafs private hack ;) and i guess we can't 
expect him to include extra documentation...however, in any 
case, debian adds a stub manpage from  templates and 
creates a /usr/share/doc with some generic info, like Changelog 
or any README from the sources.

yw...well known problems though. 
Given the above list, it should be possible to detect the distro, 
and choose from a set of modules (functions) the proper one 
to get the package list, or whatever comes near to that.

The debian package lists contain also descriptions 
and dependency lists too. For ex,

Description: nice and fast file manager for the GNOME desktop
 GNOME Commander is a fast and powerful graphical filemanager for the Gnome
 desktop environment, it has a "two-pane" interface in the tradition of
 Norton and Midnight Commander.
Homepage: http://www.nongnu.org/gcmd/
</q>

Many 'packages' are only virtual, that is, they contain only dependencies
to other packages (like gnome-desktop), so it's not trivial to tell how many
stuff  really is included (besides the question what's a 'stuff' at all). Each
llist (binary, source) is 6.6 MB now in a standard testing,  but you can add
much more sources than only the debian servers,  of course. There are many
projects which host their private little  debian archive themselves, like 
http://download.videolan.org/pub/videolan/debian/
