Statically compiling something means that you get an executable application
that has no dependencies on any libraries. So although the local machine
might only have glib 2.0.6, you could compile it on another machine against
2.3.6 statically and then copy the resulting (sizable) binary to the 'legacy'
Simply put, it merges all the required libraries (what you would see when you
type 'ldd \sbin\syslog-ng' into a single independent file that can run on
it's own steam.
To do this, compile as usual syslog-ng on a similar but more up-to-date
machine but also pass '--enable-static-linking' to './configure' when you run
it. After it compiles instead of the usual 300kB binary you will get a file
that is several megabytes in size (the glibc library and others all all
included in a single package).
