As far as I know, the problems with running 64-bit R on windows are due to
the lack of a well-developed, 64 bit minGW compiler. Therefore I would
imagine that the packages that may have trouble installing under the
experimental 64 bit build are those that include either C or Fortran source
code that needs to be compiled. You may also find that you need to compile
packages yourself-- prebuilt 64 bit versions for windows may not be
available on CRAN.

MacOS/Unix/Linux shouldn't have a problem with running 64 bit R and building
64 bit R packages-- this is because the GNU project provides a very mature
set of 64 bit compilers that these systems can use. I personally use 64 bit
R on Mac OS and have had no problems developing and installing packages for
the 64 bit system.
