Title:
  x11 dllmap points to unversioned library

Status in “mono” package in Ubuntu:
  Fix Released
Status in “mono” source package in Precise:
  Fix Released

Bug description:
  /etc/mono/config contains the dllmap for libX11 but it points to the .so
   <dllmap dll="libX11" target="libX11.so" os="!windows" />

  the .so is only included in libx11-dev.
  it should point to the versioned .so.6 contained in libx116

  TEST CASE:
  compile this with dmcs:

  $ cat libx11.cs
  using System;
  using System.Runtime.InteropServices;
  class X11Test
  {
      [DllImport ("libX11")]
      static extern void XAllPlanes ();
      static void Main(string[] args)
      {
        XAllPlanes ();
      }

  }

  $ dmcs libx11.cs
  $ ./libx11.exe

  Unhandled Exception: System.DllNotFoundException: libX11.so
    at (wrapper managed-to-native) X11Test:XAllPlanes ()
    at X11Test.Main (System.String[] args) [0x00000] in <filename unknown>:0
  [ERROR] FATAL UNHANDLED EXCEPTION: System.DllNotFoundException: libX11.so
    at (wrapper managed-to-native) X11Test:XAllPlanes ()
    at X11Test.Main (System.String[] args) [0x00000] in <filename unknown>:0

  expected:
  no backtrace

  FIX: this is caused by the build not finding the multiarched library
  it was fixed in -4:
     [ Jo Shields ]
     * [f77ef2f] Tweak build system to check multiarch library folder for
       libX11.so.

  REGRESSION POTENTIAL:
  the fix only adds a search path to configure.in which adds libX11.so.6 to etc/mono/config, it should not cause any regressions
