I have this:

[neteler at north grass70]$ grep geos include/Make/*
include/Make/Platform.make:GEOSLIBS            = -L/usr/lib64 -lgeos -lgeos_c

but without GEOSLIBS in the Makefile of v.buffer I get this error:

Using Fedora 16, 64bit with geos from their RPM.

Since you also have Fedora16, I wonder why it compiles for you and not for me
without GEOSLIBS in the Makefile of v.buffer.
