actually none of the subports build on 10.7, it's not only PY27... From the ​log of py37-gsl it seems to me that the first error is this one, so it could be caused by py-numpy instead.

okay, so this is the same problem as in ticket #59616

[ryandesign (Ryan Carsten Schmidt)]

The problem you mentioned in comment:1 is the one I reported in #59616, yes. But I do not know whether the one reported in this ticket is the same. The error message is not the same. That is why I reported it separately.
