The XML exchange functionality of Qpid is provided by the package qpid-cpp-server-xml which is produced from SRPM qpid-cpp. Pulp includes and delivers all qpid-cpp SRPM bits for EL6 from koji so a recent version of Qpid is available on EL6. The qpid-cpp-server-xml package is missing a dependency called 'xqilla' that is not available in base EL6 or EPEL. When a user goes to install the RPM, they get the following error message.
error: Failed dependencies:
libxqilla.so.5()(64bit) is needed by qpid-cpp-server-xml-0.26-8.el6.x86_64
xqilla is needed by qpid-cpp-server-xml-0.26-8.el6.x86_64
One workaround is the user could build the xqilla library from source.
Blocked by qpid upstream.
Created an upstream bug to track the resolution of this Qpid issue in JIRA.
XQilla is available for RHEL6 via RHN, and users should go there to get the dependencies they need to install this package.
