ORA-12547 when using sqlpus or svrmgrl as any user except oracle

Question

I have Oracle 8.1.7 and Oracle 9.0.1 installed on a Slackware 8.0 Linux box. It used to work fine, but something changed one day. I have tried with the Oracle 8 and Oracle 9 binaries with the same problem.
If I try svrmgrl or sqlplus as oracle, all is well, but no other user including root.
here's what happens, this time as root:
#/> ORACLE_HOME=/n/local0/oracle/OraHome1
#/> LD_LIBRARY_PATH=$ORACLE_HOME/lib
#/> PATH=$ORACLE_HOME/bin:$PATH
#/> export ORACLE_HOME
#/> export PATH
#/> export LD_LIBRARY_PATH
#/> svrmgrl
oracle: error while loading shared libraries: cannot open shared object file: cannot load shared object file: No such file or directory
oracle: error while loading shared libraries: cannot open shared object file: cannot load shared object file: No such file or directory
ORA-12547: TNS:lost contact
SVRMGR>
Checking the library dependencies:
#/> ldd `which svrmgrl`
libwtc8.so => /n/local0/oracle/OraHome1/lib/libwtc8.so (0x40017000)
libclntsh.so.8.0 => /n/local0/oracle/OraHome1/lib/libclntsh.so.8.0 (0x40019000)
libdl.so.2 => /lib/libdl.so.2 (0x405cf000)
libm.so.6 => /lib/libm.so.6 (0x405d3000)
libpthread.so.0 => /lib/libpthread.so.0 (0x405f5000)
libc.so.6 => /lib/libc.so.6 (0x4060b000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
Any clues appreciated

I have found a very strange combination of settings that allows regular non-administrative user logged in via RDP to eject the removable drive:
1) gpedit>Computer>Administrative Templates>System>Removable Storage Access>Allow
direct access to removable storage in remote sessions.
2) Local Security Policy>Local Policy>Audit Policy>Audit Object Access = Failure
3) reboot is required.
Once these options are changed - regular user can now eject the drive. Any other Audit policy does not
allow eject.
Jeremy, I think its clear that this is not hardware/hypervisor related. Is there anything I can provide
to help track this issue to a proper resolution?
thank you!
