Stubborn Multibyte

I am working for a company in Japan. I have two RedHat 6.1J machines that I
want Postgres on. On one of them, I installed postgresql 7.0.2 RPMs off of
a CD I received, and everything works fine. The second (same OS), has given
me nothing but trouble. I installed the RPMs, and then when I tried to use
"createdb", it protested "MultiByte strings (MB) must be enabled to use this
function". All the scoop I could find about that talked about
using --enable-multibyte during configure before compilation. Hmm - can't
do that with an RPM. So I removed the RPMs, downloaded the source for
7.1.1, configured, compiled, and installed, dutifully following the
instructions in postgresql.org's multibyte.html document. These are the
commands I used:
./configure --enable-multibyte=EUC_JP --with-perl --with-odbc
make
make install
su postgres
/usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data -E EUC_JP
/usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data

Up to that point, everything was fine, except that the installation
instructions seem to think that /usr/local/pgsql/bin would somehow be added
to $PATH (all the examples of using commands specify no path). But then,
the first time I tried createdb, it said "/usr/bin/postgres: cannot locate
executable" - why it wasn't looking in /usr/local/pgsql/bin I don't know.
So I copied /usr/local/pgsql/bin/postgres to /usr/bin - if that is a bad
idea, someone let me know (I figure when I have to do hacks like copying
files and adding things to $PATH after installation, something went wrong,
but...). Then I tried createdb again, and got the same message as with the
RPMs - "MultiByte strings (MB) must be enabled to use this function"! Argh!

Does somebody have any idea what is going wrong?

Thanks in advance for any help.
