I can reproduce this error under the following circumstances:

A libltdl 2.1 or newer has previously been installed in a place where
the preprocessor and the link editor can find headers resp. library
(suitable CPPFLAGS=-I... and LDFLAGS=-L... count, too), but the
libltdl.la file is missing in the installation, and also the runtime
linker does not search the installed location of libltdl.so.7 by
default (and -R.../-Wl,-rpath,... have not been added).

Does that match your setup?  If yes, who removed the installed
libltdl.la file, and why?

Thanks,
Ralf
