Just remembered something else: do you jexec into the jail, or do
you do a proper logon (eg. ssh into the jail). I think that if you
jexec into the jail and then try to ssh, you might have a problem
because you aren't really logged in to the jail and thus have no
(psuedo) tty associated with your session..

Yes- Koen you hit the nail on the head. If I use jexec I cannot use ssh to connect to other servers. I also ran into problems with make in ports tree and using screen. However- If I ssh in I can perform all functions (ssh and make) as if it were it own system...aka- jail.
The man page should reflect this. That is...all compiling and management of the jail should be done through ssh. Only use jexec for intial configuration and emergency related work.
Thanks everyone for their response and ideas.
