Package: meep-openmpi
Severity: serious

From the kfreebsd-i386 build log for meep-openmpi:

checking whether C++ compiler accepts -march=native... yes
checking for gcc architecture flag... -march=native
checking whether C++ compiler accepts -O3 -malign-double -fstrict-aliasing 
-march=native... yes

Unfortunately the flags actually passed to the compiler are hidden in
the build log so I can't be absoloutely certain this is not a false
positive but a quick grep of the source tree makes me think it is more
likely than not that -march=native is actually being used.

-march=native is not appropriate for distro packaging as it makes the
results of the build dependent on what CPU happens to be in the build
machine and means that the resulting binaries are unlikely to work on
the minimum CPU supported for the port.
