installation from scratch is broken

I tries to install bob.math from scratch, i.e., using:

$ git clone https://gitlab.idiap.ch/bob/bob.math
...
$ python bootstrap-buildout
...
$ ./bin/buildout
...

The build succeeds, there is no compiler or linker error. However, when I try to use it, I get the following error message:

$ ./bin/nosetests

Failure: OSError (/mgunther/test_checkouts/bob.math/bob/math/libbob_math.so: undefined symbol: dggsvd3_) ... ERROR

I have seen this error being reported several times in our mailing list, too. I assume that we are missing to link against the library that contains this method.

Note that this issue is only present in the latest stable version (2.1.0). This does not occur when using older versions, e.g., 2.0.6.
