The linker complained about undefined symbols acos and dlsym. If you type
`man acos` it tells you to link with -lm. The dlsym man page is less
useful but does mention -ldl in the examples section.

(I'm assuming you are looking at the Linux man pages, which are frequently
shoddy. On BSD the man pages all have a LIBRARY section which explains how
to link.)
