There might be one, but that doesn't really help us to make the
package(s). It is helpful for the creator of the Portfile to know
which steps are needed, but one cannot just use a script
out-of-the-box.

I guess that the gcc code tree isn't large enough to be an issue even on current SSDs, and that unpacking it is only an issue on HDDs so slow that you'd be handicapped by them anyway?

(Talking about libgcc compile time ... I believe it must take over 24
hours to compile libgcc on iBook G4 and then it breaks anyway. Then
Jeremy updates files, so another day ... and so on. I've been trying
to install a working compiler on Leopard since Sunday; no success
yet.)

It's not about the time needed to extract files. But I think it took
me somewhere between one and two hours to cross-compile gcc (Intel
Core 2 Duo from 2009). And then another two hours just to perform
exactly the same compilations again in steps (e) and (g) which could
have been avoided entirely. (Please don't take the numbers about the
time it took for granted. All I remember is that it was looooooooooong
and that I could have avoided much of the compilation time if I could
repeat the compilation from the same tree.)

Sure, take the 6-core Mac Pro with an SSD an nobody will care about
the optimisation any longer, but that's still not the excuse for
making things inefficient ;) Then again it's still better to have a
non-optimized installation that gets you the result than not having
the software available in the first place.
