Forum OpenACS Q&A: Server startup failed: Error during bootstrapping

I have configured AOLserver/3.3.1 with POstgreSql 7.4.13
When starting the AOLserver i got the following error:
.
Server startup failed: Error during bootstrapping
command "ns_db" is not enabled
while executing
"ns_db pools"
(procedure "db_bootstrap_set_db_type" line 61)
invoked from within
"db_bootstrap_set_db_type database_problem"

Checked the following
1) .bashrc contains:

export PATH=/usr/local/bin/:/usr/local/pgsql/bin:$PATH
export D_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/pgsql/lib

2)found possible cause

$ ldd /usr/local/aolserver3.3oacs/bin/nspostgres.so

output:
linux-gate.so.1 => (0xffffe000)
libpq.so.3 => not found
libc.so.6 => /lib/libc.so.6 (0xf7ea9000)
/lib/ld-linux.so.2 (0x56555000)

Strange: file libpq.so.3 is in $LD_LIBRARY_PATH

3) How can I recompile nspostgres.so?

Any suggestions?

Andrew,

Thanks for your reply.
1) AOLserver is started as follows:
/usr/local/aolserver3.3oacs/bin/nsd -f -t \
/web/projop/etc/config.tcl -u projop -g projop

2)
Indeed , it's een type error regarding to $LD_LIBRARY_PATH
3) Verified that it is in fact seeing the environment variables above.
4) I have installed project-open (see project-open.com) which refers to these 'old' AOLserver and PostgreSQL.
5) I shall compare my config to a known-good config file regarding to database pools.

Thanks and regards,
Ram
