That is true, but the only problem I see with snapshots is, if
maintainer is busy you can't do anything except maintaining your own local
port version on your box. And anyone using these SCM ports is the one
who knows things can go wrong often, and this is only for development
use.

Cool, would like to see the results of your experiments :).

I agree.

Gentoo GNU/Linux which is a source-based GNU/Linux distribution has this
feature available, what is different in that is, that it uses a separate
root for recording the packing list port and optionally creating a
package.
Maybe we can introduce a hack in ports system like by adding some
variable like 'USES_DYNAMIC_PLIST=yes' in Makefile, which fill let the
port first installed with DESTDIR=/var/tmp/ports/${PORTNAME} and then a
packing list is generated and then finally whole tree is moved to
${PREFIX}, hmm...? What do you say ?
Thanks for you replies.
Ashish Shukla
P.S. do you've any ideas about when a discussion on this subject took
place on this list, hmm..?
