roswtf and rpath problems in fuerte

I recently noticed that running roswtf on every package that I have produces errors related to rpath and the linker. For example, following the tutorial on creating ros packages here you create a new package by running the command

roscreate-pkg beginner_tutorials std_msgs rospy roscpp

Then if I cd to the beginner-tutorials directory, and run roswtf, I get the following error:

Loaded plugin tf.tfwtf
Package: beginner_tutorials
================================================================================
Static checks summary:

Found 1 error(s).

ERROR The following packages have rpath issues in manifest.xml:
* beginner_tutorials: found flag "-L/opt/ros/fuerte/lib", but no matching "-Wl,-rpath,/opt/ros/fuerte/lib"
* std_msgs: found flag "-L/opt/ros/fuerte/lib", but no matching "-Wl,-rpath,/opt/ros/fuerte/lib"
* roscpp: found flag "-L/opt/ros/fuerte/lib", but no matching "-Wl,-rpath,/opt/ros/fuerte/lib"

The question here seems to indicate that I should not be using -L commands within the export tag. I don't have any references to export or cpp in any of the manifests that produce these errors.

Basically every package I have written produces these same errors. What is causing this? What else should I be including in my manifest.xml?

EDIT

Adding the following line to the manifest (per manifest documentation) does not improve anything:

<export>
  <cpp cflags="-I${prefix}/include" lflags="-L${prefix}/lib -Wl,-rpath,${prefix}/lib -lros"/>
</export>

Explicitly specifying the -rpath directory using

-Wl,-rpath,${prefix}/lib,-rpath,/opt/ros/fuerte/lib

Removes the error for the beginner_tutorials package. But I am still getting errors for std_msgs, and roscpp. Is there a bug in roswtf? Should there be something else in the manifests for these packages?

Clearly, this isn't causing much of a real problem, but the "ERROR" note is definitely unsettling.

Note, I just found this link from ros-users that explains -rpath and -Wl very well. Although, my question still stands, is there a problem with roswtf?

Maybe this documentation will help.

EDIT: The export changes need to be made in the beginner_tutorials, std_msgs and roscpp packages.

To get that fixed, someone needs to open defect tickets for those packages.
