cesm1_0_4 does not take fpftcon file in ascii format

[drosa@lbl_gov]

Following the code, cesm1_0_4 seems to complain about the fpftcon not being netcdf but the ccsm from a ncar archive i am using takes the ascii.
Is there an option to set to fix this?

this is the file:

be1105en% grep fpftcon lnd_in
fpftcon = '/glade/scratch/drosa/drosa_gig_inputs/pft-physiology.c100226'

be1105en% file /glade/scratch/drosa/drosa_gig_inputs/pft-physiology.c100226
/glade/scratch/drosa/drosa_gig_inputs/pft-physiology.c100226: ascii text

and this is the error:
