Dear Dan,

Thank you for your feedback.

I have run Linux Application Checker on picasa-2.7.3736-15.i386.rpm and 
have got the following Summary:

Some compatibility problems detected

    * There are 11 of 27 distributions that provide all the required
      libraries and interfaces.
    * The Application uses 10 external libraries incompatible with LSB 3.2.
    * The Application uses 7 external libraries without using interfaces
      in those libraries. The Application would be more portable if it
      is fixed to not use unneeded libraries.

The second line presents the summary of LSB compliance of the 
application under test and it contains a hyper link to the list of the 
"10 external libraries incompatible with LSB 3.2". More details are 
available at the "LSB Certification" tab.

Do you mean to extend this information? Or may be to make its 
representation more visible?

We have the appropriate bunch of LSB packages as well. We discussed it 
and decided to promote the tarball first of all because of developers 
who are not allowed root access.

The Linux Foundation provides software repositories since LSB 3.1 Update 1.

More details are available at 
http://www.linux-foundation.org/en/RepositoryInfo, which, I guess, is 
the wiki page Mats mentioned.

It would be good if we update this information and publish at the new 
LDN to make it more visible to end-users.

That is true.
