I'm trying to X compile on a solaris amd64. I run:

./build.sh -u -U -R ../release -T ../meteor-tools -O ../obj -m i386 release

and get:
./build.sh: bad substitution

Changed the shell in build.sh to bash it goes further but eventually 
craps out with:

===> build.sh started: Wed Apr 19 11:57:41 BST 2006

_THISDIR_="${this}" "$@" ${target}; }; _makedirtarget tools obj
*** Error code 1

Stop.

Any ideas how I can get this to x compile on solaris?
