failed: ERROR OCIEnvNlsCreate. Check (everything)

We're trying to run a Perl program to connect to an Oracle 10 instance, on a
RH box. From the xterm it runs fine- connects, R/W, everything is ducky. no
issues whatsoever.

Then we tried it from a browser (apache server) and it's been a nightmare
for days. After hours of research and trials, we finally managed to get past
the "Cannot load Oracle.so"errors by modifying the ld conf file in /etc.,
rebuilding the DBI, etc.

Now we've graduated to failed: "ERROR OCIEnvNlsCreate. Check (everything)"
which basically says (*something* is wrong).

We went on a second research expiditon, and checked permissions, versions,
modified ENV vars for NLS, yet nothing seems to help; we just keep getting
this same message. The fiull message suggests a problem with ORACLE_HOME,
ORA_NLS10, NLS_LANG,  and "etc" which we interpret to mean (anything at
all).

We populated NLS_LANG to match *locale*. We also tried several other options
like america.american, etc.

The error occurs at the Connect() step. I threw it into an eval{} block and
checked perlvars for messages, but they were the same as the fataltobrowser
message below.

Finally, we use the same DBI to connect just fine from a browser to mysql.
So we know the DBI is at least functioning for some DBDs.

Any advice on howe to isolate this to a file or conf value, etc would be
most welcome!

Here is the info we can extract to try to get an idea of what it doesnt
like:
