 You probably don't want to specify just these CFLAGS. You probably want to
 specify all of the CFLAGS that MacPorts wants the port to specify. They're
 in the `${configure.cflags}` variable. `-arch` flags are not included in
 that variable; to add those, add `[get_canonical_archflags cc]`. For
 `get_canonical_archflags` to do universal builds properly, a universal
 variant (at least an empty one) needs to be stated prior to that line
 (`variant universal {}`). The same probably applies to CXXFLAGS (if this
 port contains C++ parts) and LDFLAGS. The makefile portgroup, which this
 portfile already includes, is supposed to help you do all this more
 automatically; the fact that it's not working suggests a bad interaction
 between the makefile portgroup and the port's build system that should
 probably be solved by either specifying some makefile portgroup variables
 properly or patching the build system.
