when lua is being invoked from vim, the following error message shows up:

        E370: Could not load library liblua-5.1
        Lua library cannot be loaded

Fix: Patch as in the attached file. Patch details:
 Summary

* This is a patch for <http://svnweb.freebsd.org/ports/head/editors/vim/Makefile?revision=335790>
  (Ports editors/vim r335790)
  to fix the following error when lua is being invoked from vim:

        E370: Could not load library liblua-5.1
        Lua library cannot be loaded.

* Two files are changed: Makefile and files/patch-configure

## on Makefile

* Change CONF_OPT_LUA_PREFIX using ${LOCALBASE} to ${LUA_PREFIX}
  since <bsd.lua.mk> is assumed

* /usr/ports/Mk/Uses/iconv.mk handles existence and non-existence of
  libiconv.so: always enable "USES+= iconv"

## on files/patch-configure

* Rebuild from 7.4.110 src/auto/configure
* move definition of "vi_cv_version_lua=${LUA_VER}"
* add .so to "-DDYNAMIC_LUA_DLL=\\\"liblua-${vi_cv_version_lua}.so\\\" in LUA_CFLAGS
  for properly loading the shared library of lua from /usr/local/lib/liblua-${LUA_VER}.so
