We just ran into these two same problems, in our case the solution 
was to #include <string.h> which seemed reasonable since memset and 
memcpy are C library functions. This is on Ubuntu 10.04.02

Does anyone know what version or package of Cg is required to make 
openexr_viewers? Configure can't find it and unfortunately it does 
not indicate specifically what is needed. We installed the NVidia Cg 
Toolkit Installer from the Ubuntu repo and ran it, and it seems to 
have worked, but the configure script still says it can't find Cg.

Thanks,
