Correct: there is a continual process of testing and compilation of ports
for all supported OS versions and architectures. You can see the results
and there's also
which summarises all of the known issues within the ports tree.
However, due to resource limitations it's only ever the *default* set of
options that are used when test-compiling any port. At the moment, the
ports system uses databases/db41 (db41-4.1.25_4) as the default version
of Berkeley DB -- you can find that out by reading
As to why db41 is still considered the default -- probably because no one
has requested it be updated and there isn't a specific maintainer to take
care of bsd.database.mk. In any case, changes to the ports infrastructure
like that will require a test package build run before being committed, and
that's not a trivial undertaking. There's a ports freeze coming up prior to
the release of FreeBSD 6.3 and 7.0 so it's exceedingly unlikely to be changed
in the next month or two.

Fear not. You can install several BDB ports for different versions of BDB
simultaneously. No need to rip out any ports you've previously compiled
against bdb46 and rebuild them. You can make just apache depend on bdb44 by
a snippet like the following in /etc/make.conf:
That's assuming you want to install apache-2.2.6 -- there are several other
versions of apache in the tree, and you can use much the same sort of construct,
just changing the 'www/apache22' bit, to apply options to those ports.
See also the ports-mgmt/portconf port for a possibly more user friendly way of
doing this sort of thing.

I usually find that so long as I've accounted for anything from
/usr/ports/UPDATING, then just trying to install or upgrade the port is
successful 99 times out of 100. Only on the 100th time is it necessary to go
hunting around in bug databases and so forth.
The ports tree contains over 17,000 individual ports, maintained by a wide
variety of volunteers or (in perhaps too many cases) without any particular person
or group of people to maintain them at all. Despite this, over all the quality
and consistency of ports is generally good. There will be occasional problems

You friend is living in a dream world, I'm afraid. It is practically
impossible to have zero problems in any large collection of software packages or
ports like this. Ubuntu has it's points and a lot of people find it suits them
very well, but to my mind it is best fitted to being a point'n'click style desktop
for Windows refugees. FreeBSD (IMHO) is unbeaten as a serious Unix server platform,
but to get the best out of it, you should not be afraid of getting to grips
with command line interfaces.
