Re: Problems installing from Cygwinports

As a potential setup.exe bug, redirecting to cygwin-apps.

(The tarball in question is here:)

Start by deleting /usr/include/GL/glxext.h, that will free up your hard
drive.  Then re-run setup, choosing to KEEP libGL-devel instead of

Now, as for the cause, the only thing I can think of is that I just
started using pbzip2 for compression in cygport[1].  The bz2's are
supposed to be fully compatible, and neither Cygwin nor MinGW bzip2 have
any problems with the tarball in question.

So my wild guess is that setup uses libbz2 in a way which is
incompatible with pbzip2-compressed tarballs, as unlikely as it seems.  

Can any setup.exe authors shed any light on this?
