There was another issue also besides the fact that "-E" is not supported by all 
implementations of sed.

The script is a /bin/sh script, but uses constructs like $(...) instead of 
`...`, which is not supported by /bin/sh on Solaris, and I believe AIX and HPUX 
as well.

I suspect that it works on NetBSD and probably on Linux as well since, at least 
on Debian Linux anyway, because /bin/sh is a hard link to /bin/bash or is a 
restricted version of bash which supports the $(...) construct.

My suggestion is to either change the shell that is uses, or use the `...` 
construct to make the script portable.
