Issue #9437 has been updated by Perry Smith.


Here are my thoughts.  First, create a script shown below.  I call the script get-path

    #!/usr/bin/sh
    
    echo 'int main() { return 0; }' > temp.c
    gcc -o temp temp.c
    for i in ` dump -H temp | awk '$1 == "0" {print $2;}' | tr ':' ' ' ` ; do
      if echo "$i" | grep -s '^/' > /dev/null ; then
        echo $i
      fi
    done | tr '\n' ':' | sed -e 's%:$%%'

Now, in the configuration process, run the script and it produces output like:

    /gsa/ausgsa-p9/06/ruby/bin/../lib/gcc/powerpc-ibm-aix6.1.0.0/4.5.2:/gsa/ausgsa-p9/06/ruby/bin/../lib/gcc:/gsa/ausgsa-p9/06/ruby/bin/../lib/gcc/powerpc-ibm-aix6.1.0.0/4.5.2/../../..:/usr/lib:/lib

You can prepend any additional paths that you want, then use that where you have the -Wl,-blibpath:... argument.  I get lost when trying to figure out Ruby's build process so I'm hoping you can take it from here.

miniruby will not load and gets an error of:

```

The dump -H of miniruby shows:

```

```

Note the dependency of libgmp.  libgmp is not in /usr/lib or /lib but is in another directory that the compiler knows about via the prefix path but Ruby does not.  So the link succeeds because ld knows how to find libgmp but the execution does not because of the embedded LIBPATH (element 0 above).  This has come up before.  I can work around the issue by various ways but I thought I should open an issue.

I'm happy to help out with debug or more data.
