[R] Errors Updating Libraries (2.15)

[Rich Shepard]

   I just upgraded from 2.14 to 2.15 and have run into an issue upgrading
libraries that I've not had in previous version upgrades. For example,
trying to install reshape2 for 2.15 throws errors and I don't see what to
change to over come the problem:

> install.packages("reshape2")
Installing package(s) into
‘/home/rshepard/R/i486-slackware-linux-gnu-library/2.15’
(as ‘lib’ is unspecified)
also installing the dependencies ‘plyr’, ‘stringr’

The downloaded source packages are in

Warning messages:

   What am I not seeing here?
