As far as I understand your context, you should be OK with either
solution: after converging, you will have both PHP and FreeTDS
installed, and all should be OK.

But I know it's a kind of mind-shifting, not easy at the begining. What
helps me is generally to think backward, from the desired goal: say I
have a fully installed & configured server, with both PHP and FreeTDS.
Say someone desinstall (or broke configuration) FreeTDS. What the system
should do ? If it can recover from that point, then there is not a real
dependency between FreeTDS and PHP (even if both are needed in the end,
of course !). If the system can't recover withtout
reinstalling/reconfiguring PHP, there is some kind of dependency, and a
workaround will have to be find (perhaps it's a dedicated Technique, or
something else).

Today, with you configuration (one rule for installing PHP, one other
for FreeTDS), you don't get a working system ? Do you have some errors
to report, that could help ?

Cheers,
