try man distcc or distcc --help
I would imagine you have to supply it with arguements?
or i read their site:
http://distcc.samba.org/
"60-second instructions:
1. For each machine, download distcc unpack, and do
./configure && make && sudo make install
2. On each of the servers, run distccd --daemon, with --allow options to restrict access.
3. Put the names of the servers in your environment:
export DISTCC_HOSTS='localhost red green blue'
4. Build!
cd ~/work/myproject; make -j8 CC=distcc "
Followed those steps?
