(Almost) totally untested:
$ port install | sed 's/(active)$//' | sed 's/^/install/' | grep -v  
'The following ports are currently installed:' > my_ports.txt
<trash your partition, reformat, reinstall>
$ port -F my_ports.txt

Break down of the first line:
1. Get list of ports.
2. Strip out "(active)"
3. Prefix each line with "install" (so port -F knows what action to do  
with each port)
4. Remove the line at the top: 'The following ports are currently  
installed:'
5. Send to file.

Caveats:
1. If you, like me, always want the most recent port installed, not a  
specific one, then you can drop | sed 's/@[^+]*//'
  | into the chain of seds in line 1, and that should filter out all  
the version information (and still leave variants).
2. This list contains things that were installed as dependencies.  If  
dependencies have been eliminated since you installed stuff last,  
they'll get installed again, even though this time they're not  
needed.  MacPorts is currently working towards remedying that situation.

Personally, I just have a textfile with the ports and variants I want  
in it.

Hope it helps.
