Let's say I soft link /usr/pkgsrc to different directory structures such
as /usr/pkgsrc.current /usr/pkgsrc.old etc depending on what I want to
build.

Will this work?

Even if it does, its drawback is duplication of build of dependent
packages. So instead of soft linking at pkgsrc level, can I have say
www/firefox as a soft link to www/firefox-current and www/firefox-old etc
and build either of them by switching soft links?

Is this workable?
