The ebook ABI change has been committed to the 2.7.x series and not for
2.6.x which ships on SLED10 / SL 10.1.

[Addressbook]
AFAICT, none of the ABI break changes in ebook were pushed into
autobuild and the version on SLED10 is not ABI compatible with the one
shipping with 2.7.90 and onwards. I will poke Varadhan [on CC] who
packages Evolution for SLED10 and get back to you.

[Calendar] Clock Applet (Panel) already uses the changed APIs for
handling recurrence data [1] and no other application in SLED10 is
affected by this - the libecal SONAME has not changed and it is binary
compatible with Evolution 2.7.91.  Technically - this is akin to zero
breakage on SONAMES, rpm deps et all and code-wise, the impact has
already been handled.


[1] JP had put in the fix to the panel.
