I just tried this and got a similar result, except that I also saw
these warning/error messages preceding the reported one: 

    "eval.c", line 41.1: 1506-224 (W) Incorrect #pragma ignored.
    "gc.c", line 50.1: 1506-224 (W) Incorrect #pragma ignored.
    "config.h", line 2.9: 1506-236 (W) Macro name _ALL_SOURCE has been 
redefined.
    "config.h", line 2.9: 1506-358 (I) "_ALL_SOURCE" is defined on line 
111 of /usr/include/standards.h.

And also the this message following the reported one:

    ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more 
information.

The warnings from eval.c and gc.c did not occur for Ruby 1.6.2. It
appears to be a result of the following additions:

    #ifdef _AIX
    #pragma alloca
    #endif

which however did not cause warnings in dln.c (which file seems to be
the source of the undefined symbol; see below).

Per the last (ld) error message above, the -bloadmap loadmap shows (near 
the end):

    ld: 0711-318 ERROR: Undefined symbols were found.
            The following symbols are in error:
     Symbol                    Inpndx  TY CL Source-File(Object-File) OR
