Greetings Andreas,

Generally, it's not too hard.  I spent much of yesterday trying to create a 
Makefile.am that would allow me to build
    1 - dynamically linked executables
or 2 - statically linked executables
or 3 - both

I wanted "make all" or "make shared" to do #1; "make static" to do #2; and 
"make shared static" do #3.  My final solution (today) is to have 
Makefile-static.am to handle #2.  For #3 I can now do "make all" and "make 
-f Makefile-static static".

As an added complication, bogofilter.spec.in needs to do "make -f 
Makefile-static static install_binPROGRAMS".  Simply running "make -f 
Makefile-static all install" builds the dynamically linked versions, though 
I can't figure out why.

At the moment, I'm not motivated to attempt the chroot idea :-(
