That appears to be a problem with your installation.  xmkmf requires
imake.

DYNLOADEXT should be defined using SHLIB_EXT which is determined by the
configure code that gave the above error.  What would be the right
extension for shared libraries on your system?

That I think indicates that the necessary Fortran libraries were not
determined.

Can you send me the files config.log and config.cache you obtained by
running configure?
