Does updating libmemcached (#29350) help?

Does building with llvm-gcc-4.2 instead of clang help:

sudo port clean libmemcached
sudo port install libmemcached configure.compiler=llvm-gcc-4.2

Building with llvm-gcc-4.2 helps. Thank you!

Has duplicate #32093.

It would be really helpful if we could get the port to produce verbose make output, instead of the abbreviated output that doesn't show the actual commands it's running.

This was resolved by r88092 which updated the port to 1.0.2.

Disabled silent rules in r93697.
