Dependent modules libc.a and libpthreads.a

Hello

I am trying to install ActivePerl Pro Studio and I am seeing the following errors.

Could not load program ./setup:
Symbol resolution failed for setup because:
        Symbol ___memcmp (number 1) is not exported from dependent
          module /usr/lib/libc.a(shr.o).
        Symbol __pth_init (number 80) is not exported from dependent
          module /usr/lib/libpthreads.a(shr_xpg5.o).
        Symbol __pthread (number 81) is not exported from dependent
          module /usr/lib/libpthreads.a(shr_xpg5.o).
Examine .loader section symbols with the 'dump -Tv' command.

Upon some search, it seems that I have to download these library files? But I am not able to find the righ packages for my OS version, which is AIX 5.1.

Is there something else I can do? Is this really a library issue?

Thanks in advance

I think C compilers and libraries are sold separately by IBM. But you always have GNU C option. However, I'm not sure if GNU C libraries will be compatible here (ActivePERL is Open Source, so you may test by installing GNU C).

i found this patch bundle that has these two libraries, will install them to try.
