Ubuntu 7.10, compile issues

[Alan Murrell]

I downloaded the source for kolab-2.2-beta2, and ran the installation command.  
It threw up the following error:

----------
configure: loading cache ./config.cache
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /bin/mkdir -p
checking for gawk... no
checking for mawk... mawk
checking whether make sets $(MAKE)... yes
checking for style of include used by make... GNU
checking for gcc... /usr/bin/gcc
checking for C compiler default output file name...
configure: error: C compiler cannot create executables
See `config.log' for more details.
+ /usr/bin/make
make: *** No targets specified and no makefile found.  Stop.
+ exit 2
+ exit 2
./openpkg.boot:ERROR: script returned non-null value
----------

I have tried GCC versions 4.2, 3.3, and 2.95 (from the Ubuntu repository).  Is 
there a specific version of GCC required to compile OpenPKG?  I noticed that 
the GCC version in the Kolab sources downloaded is version 4.0; will that 
work?

TIA for your help.
