[cmucl-help] build cmucl-21b on darwin-ppc powermac G5, osx 10.5.8, gcc 4.9 fail.

[ssbb]

Hello
   i try to build cmucl-21b using cmucl-21a bins on darwin-ppc 
(osx-10.5.8, powermac G5, osx 10.5.8, gcc 4.9.4), but building fail at 
stage-3.
I have read the docs about installing and building, and proceed with 
some trials.
Cmucl-21a is installed in /usr/local/cmucl-21a and started with 
/usr/local/bin/lisp sh launcher.

At first built does not start because on my G5 `uname -m` return 'Power 
Macintosh' and not 'ppc' as build.sh expect. After correcting all the 
`uname -m` case, the build begin and proceed reaching stage-3. and some 
Errors show up:

    #<Stream for file 
"/Users/stefano/build/cmucl-21b/ppc-3/assembly/ppc/assem-rtns.assem"> 
was compiled for a fasl-file version 21A, but we need version 21B

Same error repeat for all others files:

I select [continue], loading all fasl 21A files.
Building proceed and error show again:

#<Stream for file 
"/Users/stefano/build/cmucl-21b/ppc-3/code/extensions.bytef"> was 
compiled for fasl-file version 21A, but this is version 21B
    [Condition of type INVALID-FASL]

I [continue] again and build goes to:

Error in KERNEL::UNBOUND-SYMBOL-ERROR-HANDLER:  the variable 
C:*COMPILER-NOTIFICATION-FUNCTION* is unbound.
    [Condition of type UNBOUND-VARIABLE]

At this time i select [continue] to see what happen, but situation seems 
not good.
System loads some .lisp files until:
