[R] Problem loading quantreg

[derekverley]

Hi all,

I'm trying to load the quantreg package but keep running into problems no
matter which method I have tried.  Does anybody know what this error (below)
means in plain language and what I might do to get this installed.  I have
not had problems downloading/installing/running packages in the past.

thanks in advance,

derek
