I'm trying to get Passenger working on Mountain Lion after the upgrade from 10.7, but I'm having issues when running passenger-install-apache2-module:

All the required software checks are green.

I've installed the PCRE headers as suggested in the Phusion blog post, although that was a bit of a gamble since it's aimed at Nginx issues.

Does anyone have any ideas?

Thanks, Griff

are you using a packet manager? I had the same issue with homebrew and fixed it by uninstalling homebrew and reinstalling everything. – gnzlbg Dec 3 '12 at 15:47
I'm installing Passenger from the gem. I do have homebrew installed, though I'm pretty sure that Apache, Ruby etc. weren't installed through it. Might be worth uninstalling it and trying again in any event – Griff Dec 4 '12 at 16:22
Try uninstalling boost if you have installed it with homebrew. For me that was the deal. – gnzlbg Dec 5 '12 at 17:32

This is a separate problem from the PCRE problem. Phusion Passenger uses regexp functions from the POSIX standard.

At first appearance, this error seems to be implying that OS X 10.8 does not support POSIX regexp functions. But that would be a very strange conclusion seeing that:

  • 10.6 and 10.7 supported them just fine.
  • the header file regex.h is available, otherwise you would get a compiler error about regex.h missing instead of this linker error.
  • even Apple claims to officially support it.

The only conclusion I can draw at the moment is that either your system is broken, or OS X 10.8 has become broken. I am on holidays right now, ping times to Europe and the US are over 1000+ ms, and I don't have OS X 10.8, so I cannot further analyze the problem right now. As such, short-term advice I can give you are:

  • Reinstall your system.
  • Contact Apple for support.
