I'm not sure if this counts as installing "by hand", but (assuming you 
have a network connection) you can use the menu system to see the list 
of CRAN packages, and install the ones you want from there.  If you have 
some of your own non-CRAN packages, "Install package from local .zip 
file" allows multiple files to be selected and installed.

The only combination that's not so easy is installing from source 
.tar.gz files, but a shell command to loop over *.tar.gz could probably 
be written.
