47     # libs in /lib. This is to fix linking problems when you have
48     # the .so in /lib, and the .a in /usr/lib. What happens is that
49     # in some cases when linking dynamic, the .a in /usr/lib is used
50     # instead of the .so in /lib due to gcc/libtool tweaking ld's
51     # library search path. This cause many builds to fail.
52     # See bug #4411 for more info.

54     # To use, simply call:

59     # the library, as ldconfig should usually update it correctly

1000     # root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
