[BioC] buildChromLocation with Drosophila2 Affy arrays

Dear all,

I am trying to build a chromosomal map for the Affymetrix drosophila2 array and I am getting the following error from buildChromLocation() in the geneplotter  library:

> chrLoc <- buildChromLocation("drosophila2")
Error in get(mapName, envir = pkgEnv, inherits = FALSE) :
  variable "drosophila2CHRLENGTHS" was not found

Everything else required by buildChromLocation() seem to be in the annotation package...

Any suggestions on how to proceed?

Marco
