Description nietonfir 2011-10-23 18:29:31 UTC
The ebuild builds just fine after some minor adjustements to the ebuild itself,  the php-ext-source-r2 eclass, some upstream patch and local shared memory adjustements. ;)
It seems to be that shared mutexes aren't supported on FreeBSD/OS X. The ebuild will build fine but will crash the PHP process as soon as a php page is requested. To fix this, the upstream patch ([1]) from [2] needs to be added.

Moreover, even with that patch, apc crashes the PHP process at startup because it can't allocate its shared memory segments at the default size of 32Mb ([3]). This is due to an OS X limitation: The default shared memory settings are way to conservative. Thus the user would need to tweak those to be able to use apc by setting saner values in /etc/sysctl.conf, e.g the 512MB settings config from [4]. This (needed change") could be communicated to the user via an elog message or a news item.

But I think that it may be easier to add the "mmap" USE-flag to the ~x86/~x64-macos profile (${EPREFIX}/usr/portage/profiles/prefix/darwin/macos/10.6/package.use) to circumvent that problem. And because of the not working mutexes, the default lock should be changed from "lock_pthreadmutex" to "lock_pthreadrw" as well (as everything performs better than the - fixed by the patch - file fallback [5]). ;)
