Building cvs HEAD in Mac OS X (Intel)

Hi. I tried to send this before, but it didn't end up on gmane and I  
wasn't yet subscribed to the list so I didn't see if there were any  
replies.
I'm sorry if it is a duplicate.


I'm trying to build cmucl on my computer but I'm having weird errors.
I downloaded cmucl-19e-x86-darwin and am using it to compile the cvs  
HEAD version, but it throws an error at me while building phase 3.

I have the following error in phase 3:
;;; Loading #P"/.../dev/lisp/cmucl/build-2/compiler/x86/vm.x86f".

End-of-File on #<Stream for file "/.../dev/lisp/cmucl/build-2/compiler/ 
x86/vm.x86f">
   [Condition of type END-OF-FILE]

Restarts:
  0: [CONTINUE] Return NIL from load of "vm:vm".
  1:            Return NIL from load of "c:loadbackend.lisp".
  2:            Return NIL from load of "target:tools/worldload".
  3: [ABORT   ] Return to Top-Level.

Debug  (type H for help)

Source:

And some other errors in vm:*. I also have an error in pcl:
Loading binary of FIXUP...

Unable to display error condition
   [Condition of type UNBOUND-VARIABLE]

Restarts:
  0: [CONTINUE] Return NIL from load of #P"target:pcl/fixup.x86f".
  1:            Return NIL from load of "pcl:pclload".

And some others after that. It finally exits with:
gcc -Wstrict-prototypes -Wall -g3 -Di386 -DDARWIN -DGENCGC - 
DLINKAGE_TABLE -iquote . -iquote ../../src/lisp  -Di386 -DDARWIN -

In file included from ../../src/lisp/lisp.c:18:
./internals.h:1:2: error: #error You need to run genesis (via build- 
world.sh) before compiling the startup code!



I noticed that before that, in phase 2, I have (at least) this minor  
message:
;; Loading #P"/.../dev/lisp/cmucl/build-2/assembly/assemfile.x86f".
target:compiler/x86/vm
Error abort.
target:compiler/x86/insts

This is in the logs:
; Compiling DEFINE-STORAGE-CLASSES (CONSTANT CONSTANT):

Error in function C::%%DEFCONSTANT:  Constant BYTE-SC-NAMES being

Can it be failing just due to this error? What can I do to correct it?


Thanks in advance,
