Conflicts when building two packages at the same time

["Loic Hoguin" <essen%dev-extend.eu@localhost>]

Hello,

Earlier this week I installed macppc on my iBook and, to win some time,
I launched different pkgsrc compilations at the same time. When I got
back later this day I found that two of these tried to compile gtk+
at the same time, and of course it failed for both (seems they wrote
in the same file at the same time).

Wouldn't it be possible to lock building of a package to prevent these
sort of things?

Regards,
