Compile Error

[Nathaniel L. Keeling III]

I am trying to install qmail. I have a sun sparc 5 with the new solaris
8 installed. I installed the latest version of gcc (gcc2.95). I
downloaded qmail. Issued 'gunzip qmail-1.03.tar.gz' and then 'tar -xvf
qmail-1.03.tar'. I created the qmail users and groups and then I tried
to compile qmail. I received the error '/usr/ucb/cc: language optional
software package not installed' '*** Error code 1' 'make: Fatal error:
Command failed for target 'qmail-local.o' '. What does this mean and how

can I get around this?
