valgrind 3.6.1 +mpich2 variant fails

[naromero@…]

The mpich2 variant is failing. I installed as follows

sudo port install valgrind +mpich2

Looks like the construction of the libmpiwrap is failing. See attached log file.

Quoting the relevant part from the log:

Apparently you are using mpich2 with the +gcc45 variant. The compilers in the gcc45 port do not support -arch flags as these are specific to gcc provided by Apple. Indeed, this is a combination I didn't test or even thought of.

As a workaround, the build works if you use the default variant set for mpich2. But that means mpicc will use Apple provided compilers (i.e. /usr/bin/gcc).

You can remove the +gcc45 variant with the following commands:

sudo port -n upgrade --e mpich2 -gcc45
sudo port install valgrind +mpich2

Is this still a problem with the current version?
