perl update failing

[Richard B. Pyne]

I am desperate! Perl update is failing, leaving me with a broken system 
because many other things now won't rebuild because lunar thinks that 
perl is not installed. The build fails with:

         Making utilities
make[2]: Entering directory `/usr/src/perl-5.12.1/utils'
make[2]: Nothing to be done for `all'.
make[2]: Leaving directory `/usr/src/perl-5.12.1/utils'

         Making x2p stuff
make[2]: Entering directory `/usr/src/perl-5.12.1/x2p'

make[2]: Leaving directory `/usr/src/perl-5.12.1/x2p'

         Everything is up to date. Type '/usr/bin/make test' to run test 
suite.
