Installation-trouble

Dear Postgresql-experts,

this is a desperate cry for help to all of you! I am quite a rookie concerning Unix and databases. Despite this fact I have tried to install Postgresql 7.0.3 into my homedirectory (/home/lange) on a Unix platform for a test run. Following the installation guide like a lemming everything had worked quite fine until I tried to create my first table producing this:

--------------------------------------------------------------------------------

uranus% /home/lange/pgsql/local/bin/createdb testdb
ld.so.1: /home/lange/pgsql/local/bin/psql: fatal: libpq.so: open failed: No such file or directory
Killed
createdb: database creation failed

--------------------------------------------------------------------------------

Unfortunately I don't know how to solve this problem, though - I guess - it must be something obvious.
It would be very, very kind if somebody gave some advice to me.

Thank you for helping out a clueless rookie.
Christoph Lange

PS: Those are all commands (and some results) I have used until now.

uranus% cd /home/lange/pgsql
uranus% gunzip postgresql-7.0.3.tar.gz
uranus% tar -xf postgresql-7.0.3.tar
uranus% cd postgresql-7.0.3/src
uranus% mkdir /home/lange/pgsql/local
uranus% ./configure --prefix=/home/lange/pgsql/local
Only thing that looked suspicious among all messages:
configure: warning: TCL/TK support disabled; tcl shell is not in your path
uranus% gmake
All of PostgreSQL is successfully made. Ready to install
uranus% cd /home/lange/pgsql/postgresql-7.0.3/src/test/regress
uranus% gmake clean
uranus% gmake all
uranus% gmake runcheck
All tests were ok
uranus% cd /home/lange/pgsql/postgresql-7.0.3/src/
uranus% gmake install
Thank you for choosing PostgreSQL, the most advanced open source database
engine.
uranus% mkdir /home/lange/pgsql/local/data
uranus% chown lange /home/lange/pgsql/local/data

Success. You can now start the database server using:
/home/lange/pgsql/local/bin/postmaster -D /home/lange/pgsql/local/data
or
/home/lange/pgsql/local/bin/pg_ctl -D /home/lange/pgsql/local/data start
uranus% /home/lange/pgsql/local/bin/postmaster -D /home/lange/pgsql/local/data&
