I'm using a module in Apache that requires libapr-1.0.3.8, which is in my lib/ directory, but it appears my installation (via MacPorts) is using 1.0.4.5.

Can I force Apache to use the earlier version without breaking? If so, how would I go about specifying this?

I'm inclined to think that your concerns are unfounded -- the differences between the libapr versions you've got should be non-existent. The big soname change for libapr was way back in version 0.9, and since you've got a newer version, it should be backwards compatible with the older version your module needs.

If you do think you need to force it, I'd say you might be able to force it in with LD_PRELOAD without breaking, but in practice I wouldn't risk it on a production site. You certainly can't load both versions at once, you'll get symbol collisions. I'd be fixing the module.

Thanks for the response. I agree that it's hideous. It's coming from FileMaker's mod_jk_fm as part of their PHP API. I get this when I try to include it in httpd.conf: Symbol not found: _apr_stat$INODE64. When I nm -arch all libapr-1.0.4.5 looking for apr_stat I don't get the INODE64, but I do in 1.0.3.8. Is there another way around this? Appreciate the help! – Jed Jul 19 '11 at 3:04
I think you've got an archicture mismatch in your libraries -- what does file say about the two libraries? If my surmise is correct, force-feeding the wrong one to Apache isn't going to do you any good. – womble Jul 19 '11 at 3:09
results of file: 1.0.3.8 is universal binary with 3 architectures (x86_64, i386, ppc7400), while 1.0.4.5 is dynamically linked shared library x86_64. Is there a way to rebuild apache with the additional architectures? I'm so clueless about architecture stuff. – Jed Jul 19 '11 at 13:40
ignore my last question for now. i'm trying a reinstall with +universal specified in macports to see if it works. if not, i may need to take my question to a macports forum. thank you! – Jed Jul 19 '11 at 13:51
