So it seems there are a lot of dependencies missing from my __umfpack.so:
ldd __umfpack.so
        libpthread.so.0 => /lib/libpthread.so.0 (0x00002b2cc544c000)
        libc.so.6 => /lib/libc.so.6 (0x00002b2cc5667000)
        /lib64/ld-linux-x86-64.so.2 (0x0000555555554000)

(no umfpack, amd, atlas or gfortran)
And yet compilation and linking seemed to complete without errors. Is
there any way I can get more detail about the build process of the
umfpack module, perhaps try it by hand, or try to debug it further
(more verbose output seeing all the commands run to build it etc.)?
