I updated to R 2.0.0.  As I reinstalled the bioconductor packages I received
an error message about a dependency that failed to install.  The full text
of the download/installation is listed below.  As a novice user of both R
and bioconductor, I need to understand the meaning of this type of failure
and how to solve the problem.  I appreciate any information and advice you
may have about this type of error message.


Thank you,
