The responses I got the last time I posted something to -ports
convinced me not to post there anymore. I'm still subscribed, however,
so I still see what transpires there.

Yes, indeed, thanks. It was fascinating.

I've left the Cc in as well because IIRC, Maho was heavily involved
in the upgrade of immense numbers of ports to gfortran42. The next obstacle
in math/py-numpy outlined further below may well be a missed relic of that
effort.

Yes, thanks much to both of you. Cutting the option back to just
"-x atlas" did the trick, allowing math/atlas to be skipped. Here's
what it looks like giving the desired action:

Sigh. It has *always* been that way for me. By age 15 I was already
stumbling over compiler bugs, library bugs, operating system bugs, and even
the occasional, very peculiar sort of hardware bug. It's enough to make
one believe in gremlins developing interests in areas other than aviation. :-}
In the great majority of those cases, I wasn't doing anything out of the
ordinary, but somehow I managed to trigger the bugs anyway.

Understood. As noted above, it does work correctly with the shorter

Actually, it does make sense, or at least I thought so. If a
directory for atlas exists in /var/db/pkg, presumably portmaster will
think that the port *is* installed, even if it is not, in fact, installed.
Then the +IGNOREME file in that directory ought to prevent further action
on that port.

Anyway, the math/py-numpy port now proceeds to build without bothering
with math/atlas. It quickly goes astray when it doesn't recognize that any
of gfortran4[345] has been installed--I guess there no longer is a FORTRAN
compiler included in the base system--and instead tries to use lang/g95,
which has also been installed. Of course, this won't work because the ATLAS
library needs to have been compiled with the same compiler as the programs
that use it.

I looked in /usr/local/lib and didn't spot libraries by name for
gfortran[345], so I assume they have either been renamed or included in
with the corresponding gcc libraries. What is the best way to proceed?
Will simply deleting the instances of "-lgfortran" do the job? Or do I
need to specify the library explicitly?
