problems with glib installation

[Jeff Heath <jheath1 optonline net>]

I'm trying to install gnome.  Discovered that I needed to update gtk,
then discovered that I need to update glib, and install pango and atk. 

installed glib-2.2.3 and everything seemed to go well, but when I tried
to install pango-1.2.5, I got the following error message during
configure (see below). 

checking for fontconfig >= 1.0.1... Package fontconfig was not found in
the pkg-config search path. 
Perhaps you should add the directory containing `fontconfig.pc' 
to the PKG_CONFIG_PATH environment variable 
No package 'fontconfig' found

It seems that maybe the glib installation didn't go as well as I
thought.  I'm a Linux newbie, so I'm hesitant to remove the old version
of glib (as suggested below), nor do I know how to do so.  I did a
search on files named glib* and came up with about 350.  Lots of them
glib-2.0 something. 

Is /root/.bash_profile where I should change the environment
variable mentioned above?  here's the /root/.bash_profile file: 

# .bash_profile 

# Get the aliases and functions 
if [ -f ~/.bashrc ]; then 
. ~/.bashrc 
fi 

# User specific environment and startup programs 

PATH=$PATH:$HOME/bin 
BASH_ENV=$HOME/.bashrc 
USERNAME="root" 

export USERNAME BASH_ENV PATH 


Finally, here's the /etc/ld.so.conf file mentioned above: 

/usr/kerberos/lib 
/usr/X11R6/lib 
/usr/lib/qt-3.0.5/lib
/usr/lib/sane 


Thanks in advance for any help, 

Jeff
