Binaries usually have aligned sections so removing or adding just a 
small bit (like the dependency on gdk in your case introduced by the 
LCL) does not necessarily mean a change in size.

You could also try "objdump -x /path/to/your/binary" and look at was is 
listed as NEEDED in the Dynamic Section. You'd then need to find out 
what dependencies you don't want to have and then figure out which units 
led to their inclusion. Maybe it's just a stray unit that pulls in some 
GUI dependencies.
