Very Computer

I'm attempting to install the "Apache hp hpux11" on my
HP 735/125 machine that uses OS hpux 11.0.

After issuing the command:
    #./configure --prefix=/usr/local/apache
resulted in the following output:
 + doing sanity check on compiler and options
** A test compilation with your Makefile configuration
** failed.  The below error output from the compilation
** test will give you an idea what is failing. Note that
** Apache requires an ANSI C Compiler, such as g        cd ..;
cc  -DHPUX11 -Aa

Can I proceed with the install?  Or do I have to correct the above errors?

Thanks
