Hm. Perhaps we should get rid of the directory completely
and try some .setup script hacking to figure out the right path.

Where's your libglut.so* ?

Probably you need another "-L -L..." in the csc invocation to
set the correct linker path.

The eggs are nearly all developed on Linux and naturally there are
numerous annoying differences between the platforms to make
it hard to find a portable solution. Cygwin's handling of creating DLLs
is completely different again, which makes it impossible to build
eggs on the platform. The chicken-setup machinery doesn't try to
solve all those problems, just to provide a bare minimum to download
an extension, run some commands and install the extension.
The autotools provide the necessary stuff to handle all the portabiity
issues for chicken itself, but the handling of extensions is (and will
probably stay for a while) completely platform specific. 
So currently the only solution is to hack the .setup script or compile
an extension by hand. 
The manual entry about chicken-setup being supported with cygwin
is plain wrong, I'll fix that.
