I'm building from the tar.gz and install directly. I never tried to 
build a rpm so far.
The interesting part is, that it "just worked" for you. (See below for 
my experience)

I got it to work. First on my "old" (32 Bit) machine using the strategy 
I described. (This at least *was* necessary due to a too old version of 
exiv2 lib installed from rpm on this machine, which I can't update, due 
to a slow internet connection there)

Then I tried to fiddle once again with my new 64 bit machine. The 
"trick" was that easy: Just use the installed libs, instead of the ones 
I compiled myself (and installed under /pd/foto)

This version is "just working" as expected.
What I still don't get is, why my version using my self compiled libs 
didn't work.

1.
I pointed the runtime search path to /pd/foto/libs using -R. (and 
checked with ldd, that the lib is really found there)
=> Still crashes

2.
I removed the whole /pd/foto (and /pd/libs which might contain dependent 
libs) and compiled and installed from scratch
(using -R as before)
=> Still crashes

3.
configure and compile, using the installed libs under /usr/lib(64)
=> Works

Best of all:
I installed libexiv2-0.15 in /pd/foto
This is the same version as installed using the Suse rpms:
 > rpm -q -a | grep exiv
...
libexiv2-0.15-8.2
...

But still it did crash.

Bottom line:
KPA is working again, but I don't have a clue, why I failed installing 
it during the first tries...
