installing

["Witt, Richard" <Richard Witt TTMC TTUHSC EDU>]

This may sound like a really stupid question but i am stuck and rather than
just going back and totally reinstalling the whole system i would rather
find out what i am doing wrong and try and fix it.
I am very very new to linux so bear with me please.
I have been trying to update my glib and gtk+ to the 1.2.8 version.  I had
glib 1.2.6 on there and i removed it using the gnomeRPM.  Now i am still
having problems getting the glib 1.2.8 installed.  I have unzipped it and
ran then ./configure then make then make install.  Then i tried doing the
same with the gtk+ and when i run the configure i run into an error that
says:  


Could not run GLIB test program, checking why.....
The test program compiled, but did not run.  This usually means that the
run-time linker is not finding GLIB or finding the wrong version GLIB.  If
it is not finding GLIB, you'll need to set your LD_LIBRARY_PATH environment
variable, or edit/etc/ld.so.conf to point to installed location.  Also make
sure you have run ldonfig if that is required on your system.

As i said i am VERY VERY new to linux but its something i am very determined
to learn.  I know i am probably missing something silly but could i please
get some help here? 
Thank you
