I am sorry, this was from 2.10.1 on Mac OS X 10.6, so it might be Mac-specific. The behavior is reproducible both from the shell and the GUI version of R (sessionInfo output below). It does not seem to depend on the particular package: it can be reproduced by downloading an archive of a package from CRAN to a path containing spaces and calling
install.packages("path/with spaces/downloadedPackage.tar.gz", repos = NULL, type = "source"):

> print(dl <- download.packages("gam", destdir="~/Projects/R library/tmp"))
[...] downloaded 300 Kb
     [,1]  [,2]                                   
[1,] "gam" "~/Projects/R library/tmp/gam_1.01.tgz"
> install.packages(dl[,2], repos = NULL, type = "source")
[...]

Does that mean that it has been re-designed to work with paths containing spaces on Unix-alikes?
