I got this with the gnome-core 0.28.1 SRPM, so it's an old problem. How
other people have been successful with it, I don't know.

Exactly the problem. Here are my patches. You'll need automake and
autoconf installed for them to work.

This first one is on configure.in. I'm afraid I can't give you the exact
patch or even correct line numbers for the patched file, because I
patched a bunch of other stuff there too to work on LinuxPPC's broken
glibc. Just grep for "dnl help-browser" -- it only appears once AFAIK.

This one's on the Automake source for the help-browser's makefile. It's
the only change I made to that file, so the patch should be right.

After that, you just cd to the root of the gnome-core source tree, run
automake, autoreconf, then build as normal.

HTH!
