 Yes, and we are trying, right now, to figure out a better solution.

 But, please folks, give us the OS, the version of R and whether you
 are using the release or devel branch of BioC because otherwise we
 really have no chance of helping you.

  You can download this manually and install them manually like any
  other R package.

 Well, the folks in Europe, Asia or Oz might not want to wait for us
 to serve them up from the USA (which I know is the center of
 everyone's universe :-)

 ahh, so now we see that you're on windows and btw you do need to read
 about install packages because unzipping them does not install
 them. This is covered in the R FAQ and in the Bioconductor FAQ.

  R has one set of package managment routines (and Bioconductor has a
  slightly larger set).

  you can try the following (provided of course you have an internet
  connection) 

  library(reposTools)
  install.packages2("hgu133acdf")

  which seems to work on my windows machine.

  then library(hgu133cdf)

 and you are away
