libpt2.6.4-dbg 2.6.4-1ubuntu2 (amd64 binary) in ubuntu karmic

 This package contains the shared and static debug symbols of the library
 PTLib, which is a moderately large class library that has its genesis
 many years ago as a method to produce applications to run on both
 Microsoft Windows and Unix X-Window systems. This is not the debug compiled
 version of PTLib which would yield much more detailled information as a
 compromise of benefit and compile power consumption.
