Hello Dmitry. Thank you for taking the time to respond.

Ahh. That's good to know. I had thought to look to the BIND port as a
model for a jail. But, since I'm really just trying to get both PHP4 and
PHP5 to install in such a manner as to prevent symbol collisions, I
thought that simply keeping the configure/install the same as it is
now, but substituting php, for php5 would be the most efficient, and
tidy approach. It appears that all I'm dealing with is:

/usr/local/lib/php
/usr/local/include/php
/usr/local/etc/php && php.conf
/usr/local/bin/php || pgp-cgi

Which - if I have a reasonable understanding of all this, translates to:
$PREFIX || $LOCALBASE/php no?
So I figured that ultimately both php versions & the destination system
would be happiest if I simply exchanged php for php5
(php for v.4 & php5 for v.5). But as I read your replies I get the feeling
that you believe it would make better sense to simply drop the whole
install into it's own tree -
/usr/local/php5/ - lib/ include/ bin/ etc/
While that certainly isolates the install from symbol collisions with php4.
I thought it might make it harder for other applications to find it. But
maybe I'm just making/thinking this is harder that it really is. Bear in
mind that I'm ultimately looking to make this a port, and in the
"big picture" I hope to make a single port that installs /both/ php4 & php5
in such a manner as to live and work harmoniously together - creating
make conditionals that accommodate making/installing modules/extensions
out of the ports tree with out any struggle on the users part. So the
direction I choose must take all of that into account (your experience
is /greatly/ appreciated here :)) Maybe the ultimate solution would be
to simply go the
$PREFIX/php && $PREFIX/php5 route. Thereby dropping (isolating) both
versions into their own trees. But if I understand any of this correctly,
I'll need to modify the system' environment to include these directories:
($PREFIX/php/bin $PREFIX/php/lib $PREFIX/php/include &&
$PREFIX/php5/bin $PREFIX/php5/lib $PREFIX/php5/include)

Does this make any sense?

Well Dmitry, thank you again for sharing your experience and insight.
I /really/ appreciate it. Looks like I've got alot to think about. :)

Best wishes.
