  For the source you have it, check with your own metric, there is
plenty of ways to estimate source size (raw size, line of code, number
of lines, etc ...), you use windows I don't so check there, on linux
it depends what you are looking into and how you compile it:

  That's for the static library with everything compiled in. The PIC code
used for shared libraries is larger (one less register, more complex calling
conventions). If you're worried by the size most of it can be compiled
out and the library shrinks to around 200KB (but you have only simple XML
parsing left). The memory code used at run-time also completely depends on 
your working set and what you're doing with it, linux uses demand paging
so you may use as less as 50K in practice.

  So in general your question is way too unprecise to have a canonical answer
(or were your looking at the size of the installed package with or without
the devel there is also the python bindings), and I still think you're best
to check out by yourself based on the metric you think is important.
