velox ticket

[Michael Forney]

The warning tells you what to do. It can't find libwld.so.0 since it is not in your dynamic loader's search path. You should set velox's rpath or LD_LIBRARY_PATH to the directory you installed the libraries.

Closing, since this is not an issue with swc/velox, but rather your LDFLAGS/system configuration.
