[X-Unix] Compile Error ?

[Richard]

Was trying to compile a email client, called elmo,
I do have xtool installed, and was suppose to be a easy compile,
according to the readme.txt file.

Here my output via terminal window....

FastMAC:~/desktop/elmo-1.3.2 rn$ ls

--------------
what is the problem, is it telling me, that there is no C complier installed?...
I can see ( c++ and gcc 3.3 ) listed in the /bin folder.

And according to the instruction, as I mention before...

"If you downloaded a release of elmo, unpack the archive and type:

   * ./configure
   * make
   * su -c "make install"

------------------------
No so easy....
Any help appreciated...
