php53-pear incorrectly depends upon php5?

[Marc W.]

I'm attempting to migrate from php5-* ports to php53-* ones, but when
I try to install php53-pear, it installs php5. Looking at its
dependencies, it appears it should depend upon php53, not php5:

$ port deps php53-pear
Full Name: php53-pear @20110901_3
Library Dependencies: php5

Same with php54-pear:

$ port deps php54-pear
Full Name: php54-pear @20110901_3
Library Dependencies: php5

Thoughts? Thanks,
