This looks about right to me.  On our SGI's running 6.5.8 the library sizes are:

      2.5M - libVTKCommon.so
      9.5M - libVTKGraphics.so
      6.2M - libVTKImaging.so
      1.2M - libVTKPatented.so
      1.2M - libVTKContrib.so

These were compiled with "CC -n32 -O2" (not quite any of the cases you had) and are shared
libraries (".so" vs. ".a").  I wouldn't be surprised if the "-g" libraries were a lot bigger
since there are lots and lots of functions/methods/symbols but I don't have any numbers for
those.

Hope this helps...
