As far as I know package RPgSQL is outdated. The newer package 
RPostgreSQL works with R-2.9.0 and greater. So it seems to be a good 
time to update your R version. In a few days R-2.10.0 is coming out ...

The crypt function belongs to a system library 'libcrypt'. Depending on 
your system (linux?) it should be installed already. If not, you have to 
install it (outside of R, it is a system function).
