broken python packages?

Daniel,
     Both current upstream numpy 1.13.1 and scipy 1.0.0 are no longer
buildable as fink-bld...

https://github.com/scipy/scipy/issues/7979

Upstream insists this is breakage in how we are building our python
compiler packages on Darwin. While I was originally dubious about
their argument, I suspect now that they are correct. The failures can
be reproduced using the packaging that I have placed on fink tracker
at...

https://sourceforge.net/p/fink/package-submissions/5028/

and

https://sourceforge.net/p/fink/package-submissions/5056/

by changing the line...

BuildAsNobody: false

to

BuildAsNobody: true

The failures seem to be in the linkage tests of the clang compiler as
now done in recent numpy and scipy. This issue doesn't occur on
MacPorts which is already on the newest upstream numpy and scipy
releases (although they may be building as root since their builds
default to using sandbox).
     Comparing our python compiler package patches to those on
MacPorts, the one that jumps out is...

Do we really have to eliminate setting BLDSHARED to LDSHARED as this
could potentially be something the numpy and scipy developers are
relying on being set?
