Looking at the driver script, I now see that you are already giving 
configure CONFIG_SHELL=/bin/bash, presumably as a result of past 
problems.  (The "export CONFIG_SHELL=/bin/bash" line arranges this on 
Solaris 10.)

Your build driver script also prepends /usr/xpg4/bin to PATH; is there a 
"tr" in there?  Does your interactive PATH begin with that directory?
