The speed of gcc on the PPC is known to be horribly slow. The linking
phase is as well (which seems to have prompted the ZeroLink "feature"
which puts off linking to runtime).
This isn't a fault of the processor but the compiler. In fact, at
just about every single WWDC where the ProjectBuilder/Xcode team had
a new compiler/IDE they'd show a graph stating how much closer it was
getting to the CodeWarrior compile speed.
But as someone said, this is natural of a compiler with far more than
90% of the developers working on IA-32 and a compiler in which the
"owners" appear to refuse to accept any platform specific performance
patches (mentioned somewhere on this list before).

Just curious - what is the cause of this (or what do you think it
is)? All of the following statements are based on memory so they may
be incorrect, but if they are correct, the performance makes sense
to me. I believe that Intel chips are generally better than PowerPC
for integer instructions (although the G5 is much better for
floating point instructions) and compiling is just about all integer
instructions if not 100% integer instructions. Isn't the memory in
the new Intel iMac faster than the memory in the new PowerMac?
Better integer performance and faster memory (which is often the
bottleneck) means that even with twice as many processors it's just
slightly better.
