portupgrade is seriously broken

[Maxim Sobolev]

Hi,

Looks like portupgrade not longer respects error code returned by make
when building or installing package, which results in it uninstalling
previous version of the package when the build fails and not installing
it back ignoring the error code of make install. Please fix ASAP, this
is a serious problem for anybody who uses portupgrade.

My system is FreeBSD 6.4, portupgrade-2.4.6,2, ruby-1.8.7.72_1,1 and
ruby18-bdb-0.6.4.
