For example, is there any way to get a full list of the dependencies
needed for a given package,
port-rdeps does this.

For example, the dependencies of php5:
$ port-rdeps -r php5
Dependencies of php5:
gsed
gettext
libiconv
gperf
ncurses
ncursesw
expat
libtool
automake
perl5
perl5.8
autoconf
m4
help2man
p5-locale-gettext
libxml2
zlib
bzip2
mhash
pcre

sqlite3
openssl
pkgconfig
autoconf213
gawk

separated into "These are installed (and
may be upgraded)" and "These are not installed (and will cause an
error if you try to upgrade, but will install without problem)"?
Not directly, but you can use port-rdeps in a clever series of pipes
and subshells to achieve this. For example, here I echo the
dependencies of php5 that I already installed:
$ port echo installed and \( $(port-rdeps -r php5 | sed 1d) \)
autoconf @2.64_2
automake @1.11_0+universal
bzip2 @1.0.5_2+darwin+universal
expat @2.0.1_0+universal
gettext @0.17_4+universal
gperf @3.0.4_0+universal
help2man @1.36.4_1+universal
libiconv @1.13_0+universal
libtool @2.2.6a_0+universal
libxml2 @2.7.3_0+universal
m4 @1.4.13_0+universal
mhash @0.9.9.9_0+universal
ncurses @5.7_0+darwin_10+universal
ncursesw @5.7_0+darwin_10+universal
openssl @0.9.8k_0+darwin+universal
p5-locale-gettext @1.05_0
pcre @7.9_0+universal
perl5 @5.8.9_0
perl5.8 @5.8.9_3
pkgconfig @0.23_1+universal
readline @6.0.000_1+darwin+universal
zlib @1.2.3_2+universal
$
And here, the dependencies of php5 that are not installed on my system:
$ port echo not installed and \( $(port-rdeps -r php5 | sed 1d) \)
apache2
apr
apr-util
autoconf213
db46
gawk
gsed
sqlite3
$
Instead of "port echo" I could have used any other port command, such
as "port install" or "port upgrade", and I could add variants at the
end. I already have the universal variant selected for all the
installed dependencies of php5, but if I hadn't, I could rebuild them
with that variant by using (I think -- I haven't tested):
port upgrade --enforce-variants installed and \( $(port-rdeps -r php5
| sed 1d) \) +universal
