I'm also using a sort of odd system, which puts libraries in a
nonstandard location.  What I often do is to pass the linker
options to CHICKEN for finding the libraries through environment
variables.  The advantage is that you don't need to mess around
with egg setup files, and that dependencies are automatically
installed correctly without having to interfere with the installation
process.  Here's an example (from memory, may contain mistakes):

CSC_OPTIONS="-L/usr/pkg/lib -rpath /usr/pkg/lib -I/usr/pkg/include" 
chicken-install blabla

Another option is to simply add these flags in your config.make (which
is intended for adding additions or overrides for your specific box), or
set these variables when you invoke "make" to build CHICKEN.

Since it's Windows, your option to copy the stuff might be
acceptable as well, if there isn't really much of a system-wide
installation path.

It all depends on personal preference in combination with what's
practical on your particular system, I guess.

Cheers,
Peter
