If you have the current version of ports ("sudo port sync" gets you  
them), p5-error and git-core do not depend on perl5.8 but on perl5,  
which means that either perl5.8 or perl5.10 would work. You should be  
able to forcibly uninstall them (port -f uninstall p5-error git-core)  
and then reinstall them to get them to correctly record their  
dependencies on perl5.

ghc requires perl5.8. A comment in that portfile reads "since  
correctly handling whitespace is critical, only perl 5.8 is known to  
work reliably." If you need more information than that you could ask  
ghc's maintainer or the developers of ghc.
