Problem linking help-browser

[Bernd Bartmann <Bernd Bartmann picard isdn cs tu-berlin de>]

Hi!

Today I tried to compile gnome. I checked out the latest versions from CVS
and build Imlib and gnome-libs without problems. But while trying to compile
gnome-core the following messages appeared:

gcc -I/opt/gnome/include -Wall -L/opt/gnome/lib -o gnome-help-browser gnome-help
win.o gnome-help-browser.o toc2.o toc2-man.o toc2-ghelp.o toc2-info.o docobj.o m

I think these gz* functions are in zlib and zlib is definitly installed on my
machine. I'm running RedHat Linux 5.0 with all updates from RedHat and
rhlabs. gtk-0.99.4 is also installed.
So where is the problem?

Thanks in advance!
