[molpro-user] Unknown df_basis_exch Error

[Harvey Wasserman]

Hi,

On our Cray systems using a build of version 2010.1.26, a user gets the error

                                   MP2-F12 implementation by H.-J. Werner, 2007

                   Density fitting integral evaluation by F.R. Manby, 2003,2007, G. Knizia, 2010

 Unable to assign basis for exchange fitting.Please specify DF_BASIS_EXCH
 ? Error
 ? Unknown df_basis_exch
 ? The problem occurs in f12_default_bases

Could someone suggest what this might be from?  Apparently, the job runs
successfully elsewhere.  Thanks in advance.
