Problem with File::Tem (p5-ExtUtils-CBuilder/gcc and some others)

[freebsd at tern.ru]

Hello Olli,

Thank you for your reply and suggestion. It looks worth doing.
But after finding the reason of the  problem  I've successfully built
and installed problem ports.
While  digging  I've  seen similar problem in the Internet without any
solution.  So, I suspect, that this info would be interesting for some
other people.
Also,  I'm  curious  if  the  affected FreeBSD ports can be patched to
work around this problem automatically. The error "no gcc or CBuilder"
does not look suitable in this case.

With best regards,
Alexandre Krasnov.

oh> WRKDIRPREFIX?= /space/portbuild
