${destroot} is not set to correct value in pre-destroot

[jeremyhu@…]

My /opt/local/var/macports/build was a dead symlink, so ~/.macports was used instead. This worked for most cases, but not destroot in pre-destroot:

pre-destroot {
               xinstall -d -o root -g admin -m 775 ${destroot}${prefix}/var/lock
}

${destroot} was still /opt/local/var/macports/build/... instead of ~/.macports/opt/local/var/macports/build/...

Should hopefully be fixed by r54706, please test.

It's been a fortnight, and it's fixed AFAICT.
