multiple versions of docbook et al.

[David J Brooks]

While doing some pruning on my ports I noticed these:
docbook-1.3: ok
docbook-241_2: ok
docbook-3.0_2: ok
docbook-3.1_2: ok
docbook-4.0_2: ok
docbook-4.1_2: ok
docbook-4.2: ok
docbook-xml-4.2_1: ok
docbook-xml-4.3: ok
docbook-xml-4.4: ok

Do I _really_ need all those versions of docbook(-xml) ? Is there any 
compelling reason not to remove all but the latest versions and use pkgdf -f 
to point everything else to those?
