math/blas linking to gfortran with LDADD?= -lgfortran

Would you elaborate, please?  Where is a transcript showing the linking failure?
Would you mail it to me off-list?

I don't find this to be the case.  Perhaps you could provide listings for
`ldd -a /usr/local/lib/libblas.so.2`, `objdump -x
/usr/local/lib/libblas.so.2`, and
`make -C /usr/ports/math/blas -v -d l deinstall clean all`,  with and
without your change, off-list?

?  USE_FORTRAN=yes ==>  USE_GCC=4.4

You don't see any relevant undefined symbols in the blas libraries?

With regards to your statements about math/lapack and profiling: it
has been the case for some time that this port has built and installed
these libraries by default, perhaps because this port has mainly been
used by people concerned about numerical linear algebra and concrete
measures of performance.  I recently added the statement you quoted to
allow users to avoid these libraries -- it intentionally mirrors the
similar statement in the allied port math/blas, where the form is is
dictated by the use of bsd.lib.mk to build the libraries.  Given the
typical use of these ports, I don't think it is unreasonable to enable
profiling libraries by default.  But if you don't like it, you can now
easily opt out.
