Problems during ethereal installation

Hi,

i am trying to install ethereal on my RedHat9 machine.
I already installed atk. glib, gtk+ and pango, which is necessary for ethereal.
I think i saw an error message when installing gtk+, it was something like ".bashrc - No access"
Alright, during ethereal installtion, i get tons of error messages, here is the part of the config.log, where some errors appear:


configure:9435: checking for GTK+ - version >= 2.0.0

And alot more of the parse and syntax errors.
Might there be a problem with PKG_CONFIG_PATH or something?

Please, if possible give a step by step instruction, that would be the easiest way for me.

Thanks alot!
