Solaris has two shells named sh, /bin/sh (hardlinked to /usr/bin/sh)
and /usr/xpg4/bin/sh.  The latter is POSIX compliant[0] and can run
Psi's configure script; the former is not and can not.  AIUI, /bin/sh
can't be replaced as that would break pre-POSIX shell scripts, and the
prescribed way to run a POSIX shell script on Solaris is to specify
/usr/xpg4/bin/sh.

[0] At least, I _think_ it's POSIX; "man sh" calls it a "standards
compliant shell" as opposed to /usr/bin/sh.
