It appears that `R CMD build` cannot handle spaces in the path when building
packages for distribution. For instance:

[ellis at net-78815 ~/Bayesian Networks]$ R CMD build bnsl
* checking for file 'bnsl/DESCRIPTION' ... OK
* preparing 'bnsl':
* cleaning src
* removing junk files
* building 'bnsl_0.0.1.tar.gz'
tar: Networks/bnsl_0.0.1.tar: Cannot stat: No such file or directory
tar: Error exit delayed from previous errors
tar: Networks/bnsl_0.0.1.tar: Not found in archive
tar: Error exit delayed from previous errors
Error: cannot open file 'bnsl/DESCRIPTION' for reading
[ellis at net-78815 ~/Bayesian Networks]$ 

Results in a file named "Bayesian" (that appears to be the uncompressed tar
file) in ~/. I suspect some missing quotes somewhere.
