Let's say you get the following error message:

• checking for GLIB - version >= [version number]...
• *** 'pkg-config --modversion glib-2.0' returned [version number], but GLIB ([older version])
• *** was found! If pkg-config was correct, then it is best
• *** to remove the old version of GLib. You may also be able to fix the error
• *** by modifying your LD_LIBRARY_PATH enviroment variable, or by editing
• *** /etc/ld.so.conf. Make sure you have run ldconfig if that is
• *** required on your system.
• *** If pkg-config was wrong, set the environment variable PKG_CONFIG_PATH
• *** to point to the correct configuration files

Possible solution: Type in:

• export LD_LIBRARY_PATH=/usr/local/lib

Note: It is not recommended to mess around with LD_LIBRARY_PATH.

Replace /usr/local/lib if necessary. Then run ./configure again:

• ./configure
