Compiling ROOT version 5.28/00 as universal binary for Mac

Dear Fons,

Since it is possible to compile Mac applications as universal binary I would appreciate if you could make the upcoming production version root_v5.28/00 available as universal binary (32bit and 64bit) for both Leopard and Snow Leopard.

The reason for my request is that R for Mac OS X is available as universal binary for (Snow) Leopard, and thus my package “xps” is built on the Bioconductor servers as universal binary, too. However, since the servers (running Leopard) have currently only installed the root binary for 32 bit, only the 32 bit version of “” is functional, while many Mac users prefer to run R in 64 bit mode.

Thank you in advance.
Best regards
