I did a portupgrade -f lang/php5, and that did the trick! I can now load 
php extensions such as mhash and pgsql which use libthr without dumping 
core.

I guess this should have clued me in:
# ldd /usr/local/bin/php
...     
         libc.so.6 => /lib/libc.so.6 (0x284a3000)
...     
         libc.so.7 => /lib/libc.so.7 (0x285b4000)

After the portupgrade ldd shows only libc.so.7

Thanks!
