libc6-dev conflicts with libpthread-dev

Thanks for the bug report.

I'm closing this bug because it has been fixed in Feisty.

pth (2.0.7-3) unstable; urgency=medium
 .
   * Added divertion for /usr/lib/libpthread.a in libpthread-dev
     (Closes: #379413).
   * Renamed libpth2 to libpth20 and libpthread2 to libpthread20 to match the
     soname.
   * Removed lintian overrides.
   * Bumped shlibs.
   * Added libpthread20 as depends to pth-dbg.

I'm sorry, but this still affects Edgy, and Feisty is not out yet!
