[postgresql-7.0RC1] relocation error under solaris 2.6

pls forgive my poor Engilsh.

 our system is Sun Enterprise 3500 (solaris 2.6)

 I installed PostgreSQL 7.0RC1 with following configure.
 before building, I put following line in .profile file

   export LD_RUN_PATH=/usr/local/pgsql/lib

 then

   configure --enable-multibyte=EUC_KR --with-maxbackends=64 --with-odbc
   gmake
   gmake install

 and then

   initdb -E EUC_KR

 then I run postmaster

   postmaster -i -D/usr/local/pgsql/data -B 4096 -o '-S 3072' &

 but when I run createdb or createuser etc.. relocation error occured.

   [pgsql@sleds11] bin 135 > createdb -E EUC_KR test
   ld.so.1: /usr/local/pgsql/bin/psql: fatal: relocation error: file /usr/local/pgsql/bin/psql: symbol PQenv2encoding:
referencedsymbol not found 
   Killed
   createdb: database creation failed

 when I use 6.5.3, there is no problem like this..
 I thought it was some kinds of Library problem.. but don't know what to do to solve this problem.. pls help me out..

 I set .cshrc file for pgsql user like this..
   setenv MANPATH /usr/man:/usr/dt/man:/usr/local/man:/usr/openwin/man:/usr/local/pgsql/man
   setenv LD_LIBRARY_PATH /usr/lib:/usr/local/lib:/usr/ucblib:/usr/openwin/lib:/usr/local/pgsql/lib
   setenv PGDATA /usr/local/pgsql/data
   setenv PGLIB /usr/local/pgsql/lib
   setenv PGDATESTYLE ISO
