I've finally had success installing tk_as_gem on my home Windows VM
and my work Windows machine. It also no longer hangs for long periods
of time. On my VM I didn't really have to do anything to make it work,
but on my work PC I have everything stored under My Documents since I
can't write to C:\. Here is what helped:

1. Upgrade to the newest RubyInstaller package (1.9.1-p378). P243 had
a bug where the compilation couldn't finish because it had run out of
memory (Errno::ENOMEM). Install the devkit from rubyinstaller.org, if
you haven't already.
2. Run gem in a Windows command prompt (cmd) window. I never got it
working under MSys.
3. Use "short filenames" (the ones with ~ in them) instead of any
file/directory name with spaces. You can find out short filenames in
cmd by running dir /x on their parent directories. I couldn't get
paths with spaces to work.
4. For convenience, I set a shell variable TCLDIR_. It was set to
C:/Docume~1/echris~1/MyDocu~1/Development/Tcl. Note that this has
forward slashes instead of backslashes! Gcc doesn't understand
backslashes. (The underscore is because I had another variable TCLDIR
with backslashes.)
5. Use the command line:
gem install --verbose tk_as_gem -- --with-tcl-dir=%TCLDIR%
--with-tk-dir=%TCLDIR%

I really hope this helps someone. Roger, I don't know if you'd be able
to fix things so it can build with pathnames with spaces, or under
MSys, but that'd be great. And thanks for the hard work of making this
a gem!
