Comment:
This package was patched before to use lesstif instead of lesstif2 which was dropped.
But I was told in irc lesstif2 would be removed from the sync blacklist and put in universe.

I compiled lesstif2 on ubuntu and I have verified that the new debian version of xpdf builds
correctly on ubuntu/dapper and that is installable on a recent dapper
system. So this package can be synced as soon as lesstif2 enters universe.
