[BioC] ReadAffy fails 64bit linux Error in .nextMethod(e1, e2) :

[Langdon W B]

I have R running on a 64 bit version of linux.
The affy package is not working.
Ie cannot open a cel file.

Any help or comments would be most welcome

                            Thank you

                                Bill
