My first guess would be some type of corruption in your R installation. mgcv is a Recommended package, hence it is part of the standard R installation. You should not need to install it separately and only use either require(mgcv) or library(mgcv) at the command line or as you have done via the GUI app package manager. You seem to be running the 32 bit version of R 2.13.x, which is about a year or so old, with 2.15.1 being the current stable release. My recommendation would be to remove your current R installation (to clean things up, presuming that it is corrupted) and replace it with a clean installation of the current release of 2.15.1 from your preferred CRAN mirror. You would also need to re-install any 3rd party CRAN packages that you might use. I would doubt that any recent OSX updates are to blame for something new, as Apple has been winding down support for 10.5 (Leopard) since 10.7 (Lion) was released. Additionally, albeit unconfirmed I believe, support for 10.5 formally ended on August 1, shortly after the release of Mountain Lion (10.8). So you should also be thinking of upgrading your OSX installation to a more recent OSX version, presuming that your hardware would not preclude that. Information on uninstalling R for OSX is available in the FAQ here: http://cran.us.r-project.org/bin/macosx/RMacOSX-FAQ.html#How-can-R-for-Mac-OS-X-be-uninstalled_003f Lastly, for any follow ups, I would recommend that you post to r-sig-mac rather than r-help, since the former is focused on using R on Macs.
