copy error

either i'm trying to hard or something is wrong here.

i have 2 postgres installations one at work 8.0.4 on windows xp and one
at home on os x 10.3.9 and postgres 8.0.3.  i took a data file and
loaded into  the installation at work with the copy command.  but when
i try the same thing here on my os x installation i get the following
error.

ERROR:  could not open file "data/pg_nor.out" for reading: No such file
or directory

the command i run is

copy mig_equip from 'data/pg_nor.out' using delimiters '|' with null as
'';

the command i used at work was

copy mig_equip from 'c:/tmp/pg_nor.out' using delimiters '|' with null
as '';

the only difference being the location of the file.

i've tried changing the location, ran with the full path, did chmod on
the file, ran dos2unix to make sure that the was not a problem with the
file format. so i'm stumped.
i'm afraid i'm missing something obvious but i can't figure it out.

any ideas?

thanks.
