The list name perl6-internals isn't the correct place to ask this question.
(as it's about perl6, not perl5, such as the perl 5.6 you are asking about)
perl5-porters is probably a better place to ask this question, so I've
Cc'd them, and set the reply to (to ensure responses move there)
I'm not sure of the best answer to your question, but someone on
perl5-porters should be able to answer it.

The problem is that your newer version of gcc is emitting output not
anticpiated in 5.6.x's build system. The simplest fix is to manually
edit 'makefile' (not 'Makefile') and simply delete the lines containing
the phrase 'built-in'. Then you can type 'make' and all should proceed
ok.

As you say you already have perl 5.8.0 available, you can do the edit
Andy describes with
perl -ni~ -we 'print unless /: </' x2p/makefile makefile
