You may have noticed that there is a new machine listed in the build reports
for the development version of Bioconductor:

http://bioconductor.org/checkResults/devel/bioc-LATEST/

The machine is called "petty" and is running Snow Leopard (Mac OS X
10.6.4).

It is important to note that this machine is NOT building the Mac binary
packages that you download from our website or with biocLite().
Those are still produced by "pelham" (running Leopard, Mac OS X 10.5.8).

We will not use "petty" to generate the Mac binary packages we distribute,
until we are absolutely certain that it is safe to do so, that the packages
build correctly and will run on all Macs running Leopard or Snow Leopard.

You may notice in the build report that some packages build without errors
on pelham but not on petty. This is likely due to configuration issues on
petty and is probably not a problem with the package itself. We will be
smoothing out these rough edges over the next few weeks.

Please let us know if you have any questions or concerns.

Thanks,
Dan / Bioconductor team
