Pound 2.5 on Mac OS X 10.6

While updating a buildout, Pound would not compile anymore. “All” I did was update it from version 2.4.4 to 2.5.

When running the buildout, which uses the package plone.recipe.pound by the way, it ended with this:

An internal error occurred due to a bug in either zc.buildout or in a recipe being used:
Traceback (most recent call last):

Looking a bit further back, I saw this:

pound.h:188:2: error: #error "You have libpcreposix, but the header files are missing. Use --disable-pcreposix"

And before that:

checking pcreposix.h usability... nochecking pcreposix.h presence... nochecking for pcreposix.h... nochecking pcre/pcreposix.h usability... nochecking pcre/pcreposix.h presence... nochecking for pcre/pcreposix.h... no

Okay, now we’re getting somewhere… Apparently I had to make sure pcreposix.h was available. However, I had already installed pcre and pcre++ via MacPorts. Google also didn’t turn up any hints on where to get the needed header file.

Luckily I remembered that I had installed Homebrew a while back. A quick

brew install pcre

solved my problem: Pound compiled and the buildout ran without problems again.
