compilation to executable and SB-BSD-SOCKETS simple-error

i can't compile a program with usocket lib

i am aware of former issues, i have compiled latest ecl from develop branch #196 (closed) #216 (closed)

compilation of example in ecl/examples/asdf_with_dependence runs fine but when #:usocket is mentioned in example-with-dep.asd file :

./example-with-dep

Condition of type: SIMPLE-ERROR Package ((SB-BSD-SOCKETS . #)) referenced in compiled file NIL
