The jobs runs normally using gcc-compiled luatex of last week:

This is LuaTeX, Version beta-0.60.1-2010061513 (TeX Live 2010) (rev 3685)
ConTeXt  ver: 2010.05.24 13:05 MKIV  fmt: 2010.6.15  int: english/english

Quite possibly -- ConTeXt originally used a lot of perl scripts but for MkIV
those are replaced by lua.

I'm using my old svn snapshot (has to be carried around firewall on USB
stick) and I haven't had time to update the stick.

My latest attempt to build failed:

This seems to be a common SS12 problem, but there are multiple
theories: 1) optimization is needed to
remove dead code, and 2) use c99 or CC to compile.

1)  enable automatic inlining with -x04

          "If you specify -g and the optimization level is -x04,
          the compiler provides best-effort symbolic information
          with full optimization." -- man cc

"Removing dead code is an optimization" so any optimization will work

$ make CFLAGS='-g -O0' zip.o
source='zziplib-0.13.58/zzip/zip.c' object='zip.o' libtool=no \
        DEPDIR=.deps depmode=none /bin/bash

2) using c99 the build fails:

CC=/opt/SUNWspro/bin/c99
CXX=/opt/SUNWspro/bin/CC
CFLAGS="-O0 -g"
export CC CXX CFLAGS
./Build --debug --disable-xetex --disable-xdvipdfmx
