ports dependency bug report: perl5

[h]

here's the bug:

cd /usr/ports/textproc/intltool && make install clean && 
cd /usr/ports/x11/libgnome && make install clean && portupgrade -a
===>  Vulnerability check disabled
===>  Extracting for intltool-0.31.1
>> Checksum OK for gnome/intltool-0.31.1.tar.bz2.
===>   intltool-0.31.1 depends on file: /usr/local/bin/perl5.8.4 - not found
===>    Verifying install for /usr/local/bin/perl5.8.4 
in /usr/ports/lang/perl5.8
===>  Building for perl-5.8.5

ports are looking for perl 5.8.4. they don't see it, so they rebuild perl5.8. 
then perl 5.8.5 gets rebuild, and it won't install coz it's already 
installed. therefore 200 ports don't get upgraded.

how do i fix this ?
