Error building CMUCL snapshot 2006-05

Hi,

I am using CMUCL version 19b to try compiling snapshot
2006-05


I used:

 src/tools/build.sh -C "" -o "lisp"


And I was given (after some compiling), this error:

/usr/home/josemaria/src/cmucl/build-2/compiler/generic/vm-ty
pe.x86f

/usr/home/josemaria/src/cmucl/build-2/code/defstruct.x86f

to 25.

Why do you want to compile the 2006-05 snapshot using 19b? 
At the
very least you'll have to load up all the bootfiles from
the 19c
directory, but I'm not really sure that will work either.

You might be able to compile 2006-05 using 19c, but that
hasn't been
tested either.

If you just want practive compile cmucl, try compiling
2006-05 from
2006-04 or maybe something a little earlier.
