GRASS 4.2 for Linux: can't access binary

Hi All,

I recently downlaoded and installed the GRASS 4.2 binaries for Linux.
I'm running Red Hat 5.2
on a SPARC Classic. I followed all of the instructions and anxiously
typed grass4.2.
Instaed of starting GRASS I received the following error message:

[dan@moose dan]$ grass4.2
/data/grass42/etc/GIS.sh: /data/grass42/etc/lock: cannot execute binary
file
Unable to properly access /home/dan/.gislock
Please notify system personel.
[dan@moose dan]$

The same message comes up when I am logged in as root.

I checked the archives of this list and noticed that some others had the
same problem.
(do a search of the archives with .gislock)
They fixed there problem by changing the permissons on the home
directory. I checked
my file permissions and they were correct. I also made sure that the
file .gislock did
not exist.

Thanks in advance for any and all responses.

Dan
