Great, in fact it turned out it was a debian tool that went nuts :) (I
was able to build _doblas by hand, so it's just a matter of

The situation is this:

- until recently, we had this command in our makefile: 'unexport
LDFLAGS' that removes any presence of the variable LDFLAGS from the
- recently, a Debian-specific tool, started adding LDFLAGS (and other
build variables) to the env, in a way no more controllable by the
- with that variable set, gfortran misses a '-shared' option and it
generates the error I mentioned in the original email
- I'm following the path to ask for that tool to be made more
flexible, so to allow to "unset" those variables, but maybe I can
workaround it patching the code (I know, I hate to diverge from
upstream, but in extreme situations...), so I'd like to ask your
guidance in thise :) it's probably something
numpy/distutils/fcompiler/ but additional clues would be awesome :)
