macport build failure

[Russell Beall]

It seems that an update to macports has broken the compiling of opensaml.

It appears to stem from an update to boost to version 1.53 which also seem to have broken some other things out there on the 'net.

According to a thread here, the error was fixable by switching to dynamic_pointer_cast:
http://comments.gmane.org/gmane.comp.version-control.monotone.devel/19593

I hacked the port to change the two references to dynamic_pointer_cast and the compilation succeeded.  Whether that was correct and will work is yet to be seen…
saml/saml2/metadata/impl/EntityAttributesEntityMatcher.cpp
saml/saml2/metadata/impl/EntityAttributesMetadataFilter.cpp

Below is the error snippet from the log file.

Russ.
