thank you for the SRPMS! I modified RPM them for mandriva 2005 LE :

(sorry it is in French, I don't know how to make multilanguages web page)
You can install all rpm using urpmi :
urpmi.addmedia photo_favre\ 
http://emmanuelfavrenicolin.free.fr/Public/Ordinateur/Mandriva/MDV2005LE/RPMS\ 
with hdlist.cz

and RPMS/SRPMS are there :

http://emmanuelfavrenicolin.free.fr/Public/Ordinateur/Mandriva/MDV2005LE/SRPMS/

for psftools I had to had some dependencies for mandriva :
BuildRequires: libblas3-devel lapack-devel octave OpenEXR-devel netpbm-devel 
libtiff-devel libqt3
-devel libhdf5_0 libfftw3-devel gcc-g77
Requires: octave libblas3 lapack OpenEXR netpbm libtiff qt

samr thing for psfcalibration :
BuildRequires: pfstools libqt3-devel
Requires: qt pfstools jhead

for psftmo :
BuildRequires: pfstools libfftw3-devel
Requires: pfstools libfftw3

I did try psfcalibration example and it works 
http://www.mpi-sb.mpg.de/resources/hdr/calibration/pfs.html

but I cannot produce a good Tone mapped jpeg output of the example, didn't 
find good parameters!

I tried

pfsin  sample.exr | pfstmo_drago03 -b 0.99 | pfsgamma -g 1 | pfsout\ 
sample.jpeg
pfsin  sample.exr | pfstmo_reinhard02 -s | pfsgamma -g 1 | pfsout sample.jpeg
pfsin  sample.exr | pfstmo_ashikhmin02 -l 0.7 | pfsgamma -g 1 | pfsout\ 
sample.jpeg

hope it is not to much out of the scope of the mailing list, anyway I though 
some mandriva user may be interested in testing experimental rpm of pfs 
stuff!
