cannot create executables

I am trying to install PROFTPD-1.2.7 on a SCO OpenServer 5.0.6 Server with a gcc-2.95.2 installed the VOLS files from http://www.caldera.com/skunkware.

The problem I am having is when I try to run ./configure in the proftpd directory I get this error:
# ./configure
checking build system type... i686-pc-sco3.2v5.0.6
checking host system type... i686-pc-sco3.2v5.0.6
checking target system type... i686-pc-sco3.2v5.0.6
checking for gcc... gcc
checking for C compiler default output... configure: error: C compiler cannot create executables.

So I then searched here for the message here seeing if anyone has had this problem before and posted it. This is the best one I found but I don't quite understand what I am supposed to do.

I then went to http://gcc.gnu.org/ to download the source for gcc.
I could not find anything that said anything about it being the source code. So I downloaded gcc-3.2.1.tar.gz and I could not install the program because my gcc compiler does not work.
When I go to configure the new gcc I get this:

# ./configure
Configuring for a i686-pc-sco3.2v5.0.6 host.
*** This configuration is not supported in the following subdirectories:
target-libffi target-boehm-gc target-zlib target-libjava
(Any other directories should still work fine.)
Created "Makefile" in /usr/scott/gcc-3.2.1 using "mh-frag"
cc: installation problem, cannot exec `as': No such file or directory
*** The command '/usr/bin/cc -o conftest -g conftest.c' failed.
*** You must set the environment variable CC to a working compiler.

What else can I try to fix this?
What is going wrong with my Gcc compiler?
When I type in gcc I get this
# gcc
gcc: No input files
So it seems to be installed and working sort of.

Thanks in advance!!

Try this suggestion - it seems to be the one that is listed the most as a fix ( adding the development libraries) - Sco - gcc

(seems to be done in all versions of OS) -
faqchest.com

I tried what the links said to do so I downloaded binutils and went to install it. I ran ./configure and it get this message

So I figured I will try installing the rpm software so I installed the RPM software and got this message

# rpm -ivh bin*.rpm
failed to open //var/local/lib/rpm/packages.rpm

error: cannot open /var/local/lib/rpm//packages.rpm

# rpm --version
RPM version 2.4.5

The second link was to show that this problem occurs in other OSs. SCO does not use RPM.

The suggestion from
pcunix.com may help.

AHHH!!!

Thanks RTM you saved me once again!!!!

I installed that file and everything works great so far!!!!

./configure worked!!

nm

Ok when I run make I run into this problem
ar[2]: Entering directory `/usr/scott/m4-1.4/lib'
ar[2]: *** No rule to make target `cru'. Stop.
ar[2]: Leaving directory `/usr/scott/m4-1.4/lib'
make[1]: *** [libm4.a] Error 2
make[1]: Leaving directory `/usr/scott/m4-1.4/lib

What is this 'cru'??
