Hmmm ... you don't need to edit the makefile, but your linker configuration or/and
your installation needs some tweaking ....

as root, type : ldconfig -p
It lists the libraries the linker finds ...
If the libs are installed, but the linker can't find them you'll
need to edit the file /etc/ld.so.conf and run ldconfig again ....

Or/And, check the gcc documentation for info about environment variables
that affect compiling/linking (info gcc).

If none of the above helps; doublecheck that you've installed the libraries and try again ....

If it still doesn't work ... I'm clueless :-(
