Hi sanlington,

I do not have gcc version 4.4 but I was able to reproduce the bug with gcc 
4.3.

The first error occurs here:
>>> obj/linux/taucs_blas_underscore_test build/linux/taucs_config_tests.h
>>> obj/linux/taucs_blas_underscore_test: error while loading shared
>>> libraries: libg2c.so.0: cannot open shared object file: No such file or
>>> directory

You need the libg2c shared library, which is part of g77 Fortran compiler = 
GNU 3.x Fortran compiler.
You should install g77 (not gfortran = GNU 4.x Fortran compiler).

On my OS (Fedora 7), it comes for example in the compat-gcc-34-g77 rpm.

Best regards,
