Hmm... are you using pkg-config? What are the outputs of
pkg-config --libs freetype2
pkg-config --libs fontconfig
This is the program that the configure script uses to find out if the installed needed programs are the correct versions and where exactly they reside. This can be overridden by passing arguments into the configure script, but pkg-config is intended to make it a lot easier.
It looks like you're installing packages into /opt/asdlab/ in their own subdirectory, so you'll probably have to modify the $PKG_CONFIG_PATH environment variable to point to each package's lib directory. Let me know if this helps at all
