Why present different size and md5 hash between the compiled code and FreeBSD's build-in binary ?

Hi,

if your source files are *exactly* the same versions used as on the
building cluster, and you have *exactly* the same compilation options,
it would still be possible to have different binaries. For example if
the files included some reference to the current time, either in some
flags in the generated .o, .a, .so, or perhaps in the source code of
auto-generated headers. Some paths referenced could also be different on
your system than on the build cluster.

In short: don't worry too much. It is normal.
