Of course.  See src/UPDATING 20070513.  libpthread is installed
as libkse, and libpthread.so is a link to either libthr.so.3
(by default) or libkse.so.3 (when DEFAULT_THREAD_LIB=libpthread).

You can still explicitly choose which library you want when building
ports by setting PTHREAD_LIBS=-lkse or PTHREAD_LIBS=-lthr.  If you
use PTHREAD_LIBS=-pthread or PTHREAD_LIBS=-lpthread, then the default
library will be used (whatever the link libpthread.so points to).
