Comment(by ryandesign@…):

 Actually, adding those default CXXFLAGS and LDFLAGS has caused problems
 when upgrading; for example, trying to upgrade the port from 7.0.13 to
 7.0.14 I now get...

 ...because some include file has changed in the new version, but
 -I/opt/local/include is telling it to look at the old version's headers
 first; if I fix the CXXFLAGS, a similar error occurs later because of the
 LDFLAGS. So I removed those again with the 7.0.14 update in r76017, and
 left just the archflags in CXXFLAGS and LDFLAGS. The port already seemed
 to know where to find the libraries and headers it needs, so there's no
 need to add that information to CXXFLAGS and LDFLAGS.
