wxgtk build error libpthred related

Today I updated my ports, after the libpthread and bsd.port.mk 
changes....the only ports that don't compile is wxgtk-common....this 
happens when trying to configure it:

[...]
checking for GTK+ version...
checking for gtk-config... /usr/X11R6/bin/gtk12-config
checking for GTK - version >= 1.2.7... Segmentation fault (core dumped)
[...]

I looked in the config.log and tried to manually compile and execute the 
test program. It compiles but dumps with the following message:

Fatal error 'Spinlock called when not threaded.' at line 83 in file 
/usr/src/lib/libpthread/thread/thr_spinlock.c (errno = 0)
