Sorry, but there is not enough information here to give you a reasonable
guesstimate about what went wrong. What are the undefined symbols? Can
you post a short code snippit that demonstrates the problem? Could you
show the build log?

Setting DYLD_LIBRARY_PATH to / is both strange and unnecessary. I assume
that you want to have the library somewhere relative to the executable,
in which case you should read earlier posts and manpages.
