Well, the above line of code (still) works for me on the current version of R/BioC... (although run-time was longer than before [now ~20hrs]). If needed, I can sent you the OrgDb library I made.

# create OrgDb package.
# Note: takes very long time (~20hrs)
> makeOrgPackageFromNCBI(version="0.0.1", author = "First Last Name <email@address.com>", maintainer = "First Last Name <email@address.com>", ".", tax_id = "312017", genus = "Tetrahymena", species= "thermophila")

If files are not cached locally this may take awhile to assemble a 12 GB cache databse in the NCBIFilesDir directory. Subsequent calls to this function should be faster (seconds). The cache will try to rebuild once per day.
