When you do a make, if you scroll back up into the output do you see 
-fpic on the command line?

You say you modified Makefile.in.Linux?  Do you use the automake stuff?

I didnt, I used the normal Makefile, which includes src/Makefile.  I 
modified src/Makefile and changed:

CXXFLAGS= $(AGGCXXFLAGS) -I../include -L./

to

CXXFLAGS= $(AGGCXXFLAGS) -fPIC -I../include -L./

and then just did:

make
