[ruby-core:60127] [ruby-trunk - Bug #9437] Build of ruby 2.1.0 fails on AIX 6.1

Issue #9437 has been updated by Yutaka Kanemoto.

ruby -v changed from trying to build 2.1.0 to -

 Hi,
 
 This is AIX's ld's behavior:
 ----from man ld
        -LDirectory
             Adds Directory to the list of search directories used for
 finding libraries designated by the -l
             (lowercase letter L) flag. The list of directories,
 including the standard library directories, is also
             recorded in the output object file loader section for use
 by the system loader unless you use
             the -blibpath, -bnolibpath, or -bsvr4 option. You can
 repeat this flag.
 ----
 So, this can not be resolved from gcc. Some open source projects are
 affected this behavior (i.e.
 http://archives.neohapsis.com/archives/bugtraq/2003-04/0385.html)
 
 Since we are not able to remove -L. at this point, we need to use
 -blibpath to avoid including '.' from search path.
 
 % gcc -print-search-dirs
 install: /opt/freeware/lib/gcc/powerpc-ibm-aix7.1.0.0/4.7.2/

 Should we add all of these directories listed in "libraries:" ?

```

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.
