No, asprintf() is a GNU glibc extension which does a malloc()+sprintf()
in a single call. I'm afraid you'll have to rewrite those bits of code
or provide an asprintf() implementation. 

-lz = zlib which is a pretty standard library. If you are not getting
any other unresolved symbols then you probably don't need it.
