 > I don't know what to do about it though. Making gmp default to using the
 +core2 variant does not sound like a good solution because that will make
 gmp slower on Macs with newer processors than the Intel Core 2 (and might
 cause it to fail on Macs with older processors than the Intel Core 2, such
 as the original Intel Core processor). I'll Cc the maintainer of the gmp
 port for help.

 mention of gmp in that bug report and it is 14 years old.

 Sorry, see comment #5 in
 [https://gcc.gnu.org/bugzilla/show_bug.cgi?id=40734 40734]

 This sort of issue is going to become more common as authors start to take
 advantage of newer CPU's to speed up bottlenecks.  Could "port install"
 check the CPU type and warn users if a recompile would improve
 performance.
