Summary:                    No rule to make target `-lltdl', needed by
`librdf.la'.  Stop.

I've found some people commenting out "-lltdl" in src/Makefile:
https://trac.macports.org/ticket/30632 - my experience was that it will compile,
however, fail at runtime when importing in a python module:

new-host-3:redland-bindings-1.0.14.1 dorgon$ python
Python 2.7.1 (r271:86832, Jul 31 2011, 19:30:53) 
[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)] on darwin

>>> import RDF
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Python/2.7/site-packages/RDF.py", line 126, in <module>
    import Redland
ImportError: dlopen(/Library/Python/2.7/site-packages/Redland.so, 2): Symbol not
found: _lt_dlclose
  Referenced from: /opt/local/lib/librdf.0.dylib
  Expected in: flat namespace
 in /opt/local/lib/librdf.0.dylib

I guess the symbol not found has to do with the patched Makefile.

What exactly is causing the build time error?

Steps to Reproduce: 
in this order:
- raptor2-2.0.6
- rasqal-0.9.28
- redland-1.0.14
download/configure/make - the error occurs when building redland-1.0.14

I've then commented out "-lltdl" in redland-1.0.14/src/Makefile:

librdf_la_LIBADD = \
  rdf_digest_md5.lo rdf_digest_sha1.lo  rdf_hash_bdb.lo \
 #-lltdl

librdf_la_DEPENDENCIES = \
 rdf_digest_md5.lo rdf_digest_sha1.lo  rdf_hash_bdb.lo \
 #-lltdl

and it compiled. Then I successfully compiled redland-bindings-1.0.14.1
--with-python

import RDF causes the runtime error shown above.
