apt-cache show php4-gd | grep ^Dep

There's a dependency on libt1-5. I presume that's a newer version of
t1lib1 based on the info from the packages. Doesn't explain why it would
be necessary for php4-gd.

I just tried this with preferences nailed to stable and then overridden to
go to testing and unstable and didn't come across a need for t1lib1.

Trying to install t1lib1 from each of the 3 just worked as well.

Try to just install t1lib1 to find out why it's not installable.

aptitude install t1lib1

Look at output for apt-rdepends. Look at reverse dependencies for t1lib1
as well.
