I ran into this myself as well. What I kinda remember was my LD_LIBRARY_PATH
was set to something that was giving priority to libm.so.1; which doesn't
defined roundf(); instead of libm.so.2.

I think I had partially set up my environment to use an older SUNWspro
(Sun's own compiler) and that was causing the issues; even though I was
compiling with GCC.  Try setting up a shell that doesn't have visibility to
/opt/SUNWspro/lib or gives priority to "/lib" first (using LD_LIBRARY_PATH).
