I googled a lot. someone mentioned about the freetype on my system is either too old or too new to the system.
I checked my freetype package has been installed already.

[root@s-c cz]# yum install freetype

Don't know about FC12 but Debian has "libfontconfig.so.1" in a package named "libfontconfig1". Might try updating it.
