This patch still needs some love. When I tried loading the library with 
the FFI:

(define libgneural (dynamic-link "libgneural.so"))

I got the error "file not found". After some thorough investigation with 
strace and LD_DEBUG=all, I got to the root of the error:

writev(2, [{"     16551:\t", 12}, {"/opt/gneural/lib/libgneural.so", 
30}, {": error: ", 9}, {"symbol lookup error", 19}, {": ", 2}, 
{"undefined symbol: fp", 20}, {" (", 2}, {"fatal", 5}, {")\n", 2}], 
9     16551:    /opt/gneural/lib/libgneural.so: error: symbol lookup 
error: undefined symbol: fp (fatal)

Global variables! fp is defined in gneural_network.c and some library 
code depends on it. I will have to track down the dependencies and make 
them independent of the global variables (is reproducible the right term 
here?). Only then step 0 (librarifying) is done.
