[Chicken-users] 1.12 on MacOS X

[Brian Campbell]

I have tried compiling Chicken 1.12 on MacOS X 10.2.6, and I get the 
following error (with context):

/bin/sh ./libtool --mode=link gcc  -O3 -fomit-frame-pointer -Wall 
-Wno-unused -Wno-uninitialized -fstrict-aliasing    -o 
libstuffed-chicken.la -rpath /usr/local/lib -version-info=0:0:0 
-no-undefined -lm extras.lo format.lo match-support.lo lolevel.lo 
tinyclos.lo script-utils.lo tcp.lo regex.lo posix.lo libchicken.la -lm
rm -fr .libs/libstuffed-chicken.la .libs/libstuffed-chicken.* 
.libs/libstuffed-chicken.*
gcc -r -keep_private_externs -nostdlib -o

.libs/libstuffed-chicken.0.0.0.dylib-master.o  -L./.libs -lchicken -lm 
-lc -install_name /usr/local/lib/libstuffed-chicken.0.dylib 
-compatibility_version 1 -current_version 1.0
ld: Undefined symbols:
_environ
/usr/bin/libtool: internal link edit command failed
make[1]: *** [libstuffed-chicken.la] Error 1
make: *** [all] Error 2

Can anyone tell me what I need to do to fix this? Am I missing some 
other required package, or what?

Thanks,
Brian
