Is there a particular reason you need the ppc64 architecture? There is no version of Mac OS X or MacPorts where ppc64 is used by default, so by using it you are likely to run into problems nobody has seen before. The only reason to use ppc64 would be if you need to run programs that need to access more than 4GB of memory.

Ports build using the compiler the port author specified. Usually this is the version of gcc provided by Xcode. It is not supported for users to change this. If you insist on trying this, then you could use the following incantation:
sudo port clean glib2
sudo port install glib2 configure.compiler=macports-gcc-4.5
A list of available compilers is coincidentally contained in this unrelated document:

This looks like this bug report:
I guess we don't yet know why it's happening.

MacPorts does not use the separate-ports-for-headers packaging strategy that some other package managers use. The headers are already included if you've installed the ports.
