When linking a program build with gfortran 4.3.0 to lapack, I get /opt/atlas-gnu_4.3.0/3.8.1/lib64/liblapack.so: undefined reference to `_gfortran_pow_r8_i4' /opt/atlas-gnu_4.3.0/3.8.1/lib64/liblapack.so: undefined reference to `_gfortran_pow_r4_i4'
See http://forums.amd.com/devforum/messageview.cfm?catid=217&threadid=90399&messid=881726&parentid=856116&FTVAR_FORUMVIEWTMP=Branch for a similar complaint.
OK, the LAPACK library was probably compiled with 4.1.2.
