dlsym, dlopen, dlerror, dlclose

     Hi.

     I'm a inexperient Apache user. I downloaded the binary distribution
of Apache 1.3.14 for AIX 4.3.1 (RS/6000) and installed it using
'install-bindist' script. But when I try to run 'httpd' or 'apachectl
start' the following error message appears:

     "Could not load program httpd
      Symbol dlsym in httpd is undefined
      Symbol dlerror in httpd is undefined
      Symbol dlopen in httpd is undefined
      Symbol dlclose in httpd is undefined
      Error was: exec format error"

     Any ideas are very welcome.
     Sorry my bad english.
     Thanks.

The 1.3.14 binary was compiled against AIX 4.3.2, which is probably the problem. I'll try to do an
AIX 4.2.1 and a 4.3.2 binary for the next release of Apache.

I have heard the same problem from other folks on comp.unix.aix, there
is no simple workaround besides compiling from source. I have no idea
how this binary was compiled.
