  Subject: [PATCH] Do not require a recompile for each new PA version in order to detect the modules.

 Changed Files: configure*
  In Ubuntu and Debian the command:
    `pkg-config libpulse --variable libdir'
  returns the path: /usr/lib/i386-linux-gnu
  But libpulse modules are located in /usr/lib.
  So, it's better use:
    `pkg-config libpulse --variable exec_prefix'/lib
  to right get the location prefix of modules.

  Version 0.9.10 also affected.
