re2 @20140110: build failure on Snow Leopard: undefined symbols

[cooljeanius (Eric Gallager)]

Re-building my ports on my new drive, and I ran into this error when trying to build re2:

I do not remember this happening previously, so I guess r115779 must have introduced it... Anyways it looks like an issue with the c++ standard library...

This issue has been reported upstream: ​http://code.google.com/p/re2/issues/detail?id=99 Though I don't know what the timeline is for fixing it.

This still happens after the update from r116435

I have committed in r116839 to install the version 20131024 on Snow Leopard and 20130622 on Lion and Mountain Lion in the meantime.

Replying to hum@…:

That works for now, thanks!
