I'm the Fedora maintainer, so those patches are my fault. :-)  One of
them makes it unnecessary to switch off brk randomization for the
entire box, if that matters to you (gcl-2.6.8-unrandomize.patch).

Also, note that the -lz problem has been fixed in CVS, and a number of
the Fedora patches have been applied as well.

That's a strange failure.  I'm going to take a wild shot in the dark
here.  Does adding -fno-strict-aliasing to CFLAGS help?
