I was building memcache 3.0.8 for PHP 5.6 from Acquia DevDesktop and I was getting error about incorrect architecture (also when I installed memcache via brew). The solution was to add "32bit" flags for the configuration script:

./configure --enable-memcache --with-php-config=/Applications/DevDesktop/php5_6/bin/php-config "CFLAGS=-m32" "CXXFLAGS=-m32" "LDFLAGS=-m32"

The error I was getting was something like wrong architecture in Unknown on line 0 in MAMP.
