Sqlnet V1 installation on SUN clients

I am trying to install SQLNET V1 from the Oracle 7.0.12 cdrom distribution on my SUN IPX running 4.1.2.

I have created a UNIX user called oracle and a group called dba. Created a home directory of /u01/home/oracle for oracle

drwxr-xr-x  5 root     wheel         512 Apr 30 10:44 /u01
drwxrwxrwx  3 root     wheel         512 Apr 30 10:44 /u01/home
drwxr-xr-x  7 oracle   dba           512 Apr 30 14:06 /u01/home/oracle
drwxr-xr-x  3 oracle   dba           512 Apr 30 10:58 product
drwxr-xr-x 11 oracle   dba           512 Apr 30 12:36 product/7.0.12

I have mounted the cdrom as:

mount -r -t hsfs /dev/sr0 /cdrom

the permissions on the directory tree down to orainst are:

dr-xr-xr-x  2 root     wheel        2048 Jan 28 21:52 /cdrom
drwxr-xr-x 32 9741     643          4096 Jan 29 06:56 /cdrom/oracle
drwxr-xr-x  2 9741     643          6144 Jan 28 21:51 /cdrom/oracle/orainst

I am running openwindows when I do this so in an xterm window I "su -" from me to "oracle".

I cd to /cdrom/oracle/orainst and type in ./orainst. ( My ORACLE_HOME is set to /u01/home/oracle/product/7.0.12 and my ORACLE_BASE is set to
/u01/home/oracle. )

The installer asks me what I want to use for ORACLE_HOME and offers me
/u01/home/oracle/product/7.0.12 as the default. I take the default, the
installed changes to the next screen and prints the error message:

sh: getwd: can't open ..

and fails. I have tried everything I can think of in terms of checking permissions, etc. and am getting nowhere. I can get the software installed if I log in as root. ( I am only installing the SQLNET V1 software, not the oracle kernel. )

Anybody run into this??!!! Anybody have any ideas as to what the problem is?

Thanks,
