make install fails for subversion

[Lou Katz]

The make runs ok
The make install chugs along until:

	chmod 755 /usr/local/libexec/apache2/mod_authz_svn.so
	[activating module `authz_svn' in /usr/local/etc/apache2/httpd.conf]
	subversion/svnversion/svnversion . /repos/svn/trunk > /usr/local/include/subversion-1/svn-revision.txt
	/usr/libexec/ld-elf.so.1: /usr/local/lib/libapr-0.so.9: Undefined symbol "pthread_mutex_init"
	*** Error code 1

	Stop in /work/local1/ports/devel/subversion/work/subversion-0.32.1.
	*** Error code 1

	Stop in /work/local1/ports/devel/subversion.



I have checked, and there is libpthread.so.20 in /usr/local/lib/pth which I have linked
up into /usr/local/lib, and it has the symbol "pthread_mutex_init".
