rhymes against wrote:

I need the following environment variables set to compile the courier
mta and authentication components, and unset to compile the dragonfly
os.  Is there a convenient way to set this up so I don't need to
remember to do and undo this every 6-8 months?
is this within pkgsrc or a separate build?

if separate - pkgsrc might simplify things if it works for you..
