The .la *isn't* the static library.  Static libs end in ".a".  A ".la"
file is just information *about* a shared library (it's a text file;
look at it and see).

I think now that you have /usr/local/lib in your /etc/ld.so.conf,
compiling without an explicit --enable-shared should probably work fine.
