arpack: Configure failed

[amitbhatia3@…]

Cannot install arpack +atlas. Configure failed. Looks like it is attempting to issue command "/opt/local/bin/gfortran-mp-5 -V" and does not like "-V". If "/opt/local/bin/gfortran-mp-5 -v" (lower case v) is issued on command line, then it seems happy.

In the future, please use WikiFormatting, fill in the Port field and Cc the port maintainers (port info --maintainers arpack), if any.

The "-V" flag is not the problem. The problem is further down in main.log when it's looking for a suitable lapack library. In my main.log I see this:

...
:info:configure checking for sgemm_ in -L/opt/local/lib -lsatlas... yes
:info:configure checking for cheev_... yes
...

Perhaps you installed arrack with the +nofortran variant?

[amitbhatia3@…]

On Yosemite, I had installed Atlas and Arpack without fortran, which is what I was trying here (Capitan). But, as you suggested, I reinstalled Atlas with fortran, and now Arpack installed fine (with fortran).

I wondered how that worked on Yosemite, because Arpack is a fortran library... In any case, I can probably close this ticket.
