can't pip install bdsf

[o-smirnov]

Trying to pip install it into a virgin virtualenv, it falls over. This smells like a packaging/dependency issue, rather than a problem with BDS* itself, so I'm reporting it here. @gijzelaerr, @Athanaseus, any ideas?

If I manually pip install numpy, then pip install bdsf gets a little further, up to:

    Building libminpack
    error: [Errno 2] No such file or directory

kern has little to do with the pip packaging of bdsf, please report the issue here https://github.com/lofar-astron/PyBDSF
