Mounting gdbe home directories with pam_mount (or otherwise)

[RW]

I'm thinking of using a gdbe home directory for  for one of my accounts. I'd 
rather not mount the partition at bootup, and logging in to another account 
to mount the partition seems a bit of a pain (three passwords).

I was looking for a workaround, and found pam_mount 
<http://www.flyn.org/projects/pam_mount/index.html> which seems to be an 
ideal solution, since it can mount an encrypted partition transparently with 
the normal login password.  It claims to work with several BSD flavours, but 
it doesn't seem to be in ports. Does it work with FreeBSD and gdbe 
partitions?
