Running R 3.1.2 on OS X 10.10.1.

I've observed that on some packages, but not all, install_version gives me an error about continuation lines. An example that I ran into:

• install_version('RcppEigen', '0.3.2.1.2') gives me an error Error: Found continuation line starting ' The RcppEigen pac ...' at begin of record.
• install_version('BH', '1.54.0-2') is no problem

It seems like an issue with read.dcf and continuation lines in DESCRIPTION that contain only a period, to indicate a blank line. The above version of RcppEigen happens to have two of these lines in DESCRIPTION, but BH does not.

I debugged read.dcf. It's called 3 times during install_version, twice to an identical file in /var/folders/... that looks like a temp directory, and once to a nearly identical path but in /private/var/folders/... Weirdly, the version in /private/var/folders/... seems to have had the period lines replaced with total blank lines, and .Internal(readDCF(...)) fails, presumably because it reads the next line as a start-of-record line.

I can download and install the old version of RcppEigen with R CMD INSTALL just fine.
