I suspect he will run into more missing libraries (such as the math
library, -lm). The issue is explained a bit in this document:

http://fedoraproject.org/wiki/UnderstandingDSOLinkChange

In a nutshell: Fedora (possibly other distributions as well) changed
the way dynamic objects are linked and implicit references are not
allowed anymore. I guess it means that the cinepaint (and/or plugin)
Makefiles (whichever version in the toolchain is appropriate) should
be adjusted to accommodate this change, which I have also ran  into. I
have manually modified all the makefiles to include all necessary
libraries, but it was a pain in the neck.
