mpich2 @1.4 Build error - build failure

[fultz@…]

While installing mpich2 I get the following error:
Error: Target org.macports.build returned: shell command failed (see log for details)
Log for mpich2 is at: /o/l/v/m/logs/_o_l_v_m_s_rsync.macports.org_release_ports_science_mpich2/mpich2/main.log
Error: Status 1 encountered during processing.

The log file states:

Could you attach the log?

It looks like you have LAM/MPI installed and it's grabbing that during the compile.. Do you have lammpi installed? If so, try deactivating lammpi and then clean/build mpich2. If that fixes it I'll mark the conflict in the portfile.

[eborisch (Eric A. Borisch)]

That log is from re-issuing the build, but no matter -- do you have LAM/MPI installed? I can recreate the issue with lammpi installed, so I'm assuming you have it. Please try deactivating lammpi and clean/build mpich2.

That indeed did work. Thanks a lot!
