Hello

I have a problem running initdb 8.0.1. I get this error message when I
try to run this command in my system:

-------------------------------------------------------------------
-bash-2.05b$ /local/opt/postgresql/bin/initdb 
The program "postgres" is needed by initdb but was not found in the
same directory as
"/local/store/bbking/.postgresql/ver-8.0.1/opt/postgresql/bin/initdb(at)386linuxlibc63".
Check your installation.
-------------------------------------------------------------------

strace shows this:

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

Some additional information:
----------------------------
We are running a system for administration of third party software on
UNIX computers (store). With this system we can compile in a master
server versions for different platforms and different versions of the
software for a platform, distribution happens automatic.

This system is well tested and works without a problem. We have been
running the last 8-9 version of postgres in this system without a
problem.

What the system does is to create a symblink to the version for your
machine (among other things).

For example:

If we install the binaries for postgres under /local/opt/postgresql/bin,
initdb in this directory will be a symblink to
"/local/store/bbking/.postgresql/ver-8.0.1/opt/postgresql/bin/initdb(at)386linuxlibc63 
and 

/local/opt/postgresql/bin/postgres will we a symblink to
/local/store/bbking/.postgresql/ver-8.0.1/opt/postgresql/bin/postgres(at)386linuxlibc63(dot)

if we are in a linux machine.

If we run the same version in a solaris machine:
/local/opt/postgresql/bin/initdb -->
/local/store/bbking/.postgresql/ver-8.0.1/opt/postgresql/bin/initdb(at)sun4os58

and 

/local/opt/postgresql/bin/postgres -->
/local/store/bbking/.postgresql/ver-8.0.1/opt/postgresql/bin/postgres(at)sun4os58

Solution to the problem?:
-------------------------

I solution to this problem will be to look for postgres under the same
directory of initdb (/local/opt/postgresql/bin in our example) and not
under the directory of the initdb symblink target. 

Any comment to this?
Thanks for your time.
