It still seems like it doesn't find the libraries it needs. Can you
provide the output of the command, from the cygdrive topdir:

find . -iname "lib*tcl"  2>/dev/null

and if you are using apt-cyg:

apt-cyg list

to see which packages you have installed. Or just make sure you have all
the packages installed that Gavin Abo mentioned. As for his procedure it
should work, though I think the patching should no longer be required
(as far as I remember from my compilation, I could be wrong). There is
also a precompiled version for Windows, but I'm guessing that it doesn't
work for you or is there a reason that you have to compile from source?

Here is the version of Make.sys is used if it helps in any way (on my
system the libraries are located in /usr/ directory) :
