* set up ssh.  to run pantasks and other programs which require automatic connections via ssh, it is necessary to make a password-free key.  you can use one of the three encryption methods listed below:
{{{
 ssh-keygen -t rsa1
 cat ~/.ssh/identity.pub >> ~/.ssh/authorized_keys
 ssh-keygen -t dsa
 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
 ssh-keygen -t rsa
 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
}}}

 * login to each of your machines to set up the known_hosts entry.

 * download the external libraries from the IPP web pages:

 wget -nH --cut-dirs=3 -L -r http://pan-starrs.ifa.hawaii.edu/project/IPP/software/ext/
 wget -nH --cut-dirs=3 -L -r http://pan-starrs.ifa.hawaii.edu/project/IPP/software/extperl/

 * unpack the ipp tarball

 tar xvzf ipp-1.2.tgz

 * enter the ipp build directory

 cd ipp-1.2/psconfig

 * check for external C libraries

 pschecklibs

 * install using psconfigure / psmake ''we need a tool to automatically build the needed libraries''

 * cfitsio and fftw3 need to have --enable-static set for configure
 * cfitsio needs to be called with 'make shared' before 'make install'
