Starting with 1.6 version of pkgdiff if you compare debug packages
and
add --details option on the command line then the tool will
automatically run abi-dumper to dump ABI of old and new shared
objects
found in the packages and then compare them by the
abi-compliance-checker tool.
hum , so pkgdiff -details doesn't use abi-compliance-checker without
abi-dumper installed ?
Yes, it doesn't. Detailed checks of ABI changes in shared objects will
be disabled in this case. They are enabled only if you install both
tools and compare appropriate debug-info RPM packages.
ah ABI Status, just appears when we compare debuginfo packages (with
-details )

Cool thanks,
pkgdiff print some errors [1] are you interested in reports ?
