Configuring T/TO/TODDR/IO-Tty-1.12.tar.gz with Makefile.PL
Now let's see what we can find out about your system
(logfiles of failing tests are available in the conf/ dir)...

ERROR: cannot run the configured compiler '/opt/SUNWspro/bin/cc'
(see conf/compilerok.log). Suggestions:
1) The compiler '/opt/SUNWspro/bin/cc' is not in your PATH. Add it
   to the PATH and try again. OR
2) The compiler isn't installed on your system. Install it. OR
3) You only have a different compiler installed (e.g. 'gcc').
   Either fix the compiler config in the perl Config.pm
   or install a perl that was built with the right compiler
   (you could build perl yourself with the available compiler).

Note: this is a system-administration issue, please ask your local
admin for help. Thank you.
