Looks like RedHat Linux from the name of the libraries.

My guess is that an f2c or g2c development package needs to be 
installed.   On a Debian system the library comes from the libg2c0-dev 
package

$ dlocate libfrtbegin
libg2c0-dev: /usr/lib/libfrtbegin.a

By the way, I would pay attention to those warnings about incompatible 
pointer types in calls to dpotrf and dpotrs.  Remember that calls to 
Fortran routines from C must pass scalars by reference, not by value.
