The configure script enables using ltdl only if it detects that ltdl.h
is available. Looks like on your system ltdl.h is present, but the
library ltdl is missing. If not, please provide the configure terminal
output.

In any case you can disable using ltdl by passing option --disable-dl to
the configure script.
