Python and SWIG support in ports?

[Craig Rodrigues]

Hi,

I am working with the upstream maintainer of M2Crypto (
https://gitlab.com/m2crypto/m2crypto ).

In the distutils that comes with Python, the swig binary is harcoded
to "swig" if on a POSIX system:

https://hg.python.org/cpython/file/v2.6.2/Lib/distutils/command/build_ext.py#l635

In our ports, we name our swig binaries things like
"/usr/local/bin/swig2.0" or
"/usr/local/bin/swig3.0".  How do we deal with this in Python ports which
use
SWIG?

If possible, I'd like to push a fix upstream for FreeBSD, if the upstream
maintainer
is OK with it.

Thanks.
