There are a number of errors in my mail below (probably caused by the
fact that I was in a hurry to leave for dinner ;-)
1) The file is configure.in, in mca/io/romio/romio/configure.in, not
Makefile.in
2) The $ in grep 'pvfs$' was added by me as a temporary hack to
prevent it from building pvfs along with pvfs2.
It's not a good solution anyway, because $FILE_SYSTEM contains things
as "nfs ufs pvfs pvfs2"
Really, the correct fix is just to use $file_system_pvfs,
$file_system_pvfs2, ...
Greetings,
