[bug-gettext] gettext and -R

[Ryan Schmidt]

Hello, I'm the maintainer of gettext and many other ports in the MacPorts 
package management system for OS X. I'm having a problem building another 
package, and I believe I've traced the problem back to gettext.

The package I'm trying to build doesn't provide a pre-built configure script or 
Makefiles, so I have to run autoreconf.

gettext 0.19.2 provides the file /opt/local/share/aclocal/lib-link.m4 which 
contains these lines:

  if test "X$ltrpathdirs" != "X"; then
    dnl When using libtool, the option that works for both libraries and
    dnl executables is -R. The -R options are cumulative.
    for found_dir in $ltrpathdirs; do
      LTLIB[]NAME="${LTLIB[]NAME}${LTLIB[]NAME:+ }-R$found_dir"
    done
  fi

I believe it is these lines that are responsible for the following value 
appearing in the Makefiles of the package I'm trying to build:

LTLIBICONV = -L/opt/local/lib -liconv -R/opt/local/lib

Because I am using a recent version of clang ("Apple LLVM version 6.0 
(clang-600.0.54) (based on LLVM 3.5svn)"), this in turn causes the build of the 
other package to fail with this error:

clang: error: unknown argument: '-R/opt/local/lib'

clang has never supported the -R flag, but it was only recently changed from a 
warning to an error.

How can we modify gettext's autotools files so that it does instruct other 
packages to use unsupported options like -R?

Thanks for your help.
