LyX executable size

[Cucinotta Tommaso]

Hi all,

is there any way to get a LyX executable smaller than 15M 
?
I'm getting it with
  ./configure --disable-debug --enable-optimization=-O
  make

but I noticed that from a lyx1.5.0-rc1patch1 .deb archive 
the executable is only 7M.

On a related note, is there a way to exclude the build of 
the included boost copy, and use instead the system one 
(compiling on Linux Ubuntu Feisty) ?

Thanks, bye,

  T.
