Hi,

Thank you very much for catching this thread.

To follow existing code which uses dlopen(), I omitted -e option.
Then, these options are used to supress some error message.

I have AIX 4.3.3 machine which is oldest in my test environment,
and it actually has dlopen(), but I think the older version AIX
would not have dlopen() (or broken?). I had prioritized the current
supported versions as matz said ( see [ruby-dev:29154]). I should
have been more carefully to support old versions.

Please give me some time to make another patch? I have noticed
the linker_flag variable you made. I will make new patch against
ruby_1_8 branch or trunk. Since I will test on various AIX versions,
it will take a little...

Thanks and best regards,
