Andi,
Is it necessary to remove these (installed RPM) package:
# rpm -qa *\Graphics\* GraphicsMagick-1.3.14-1.el6.x86_64 GraphicsMagick-perl-1.3.14-1.el6.x86_64
Or it's safe to leave them untouched, then compile-install GraphicsMagick from:
http://nchc.dl.sourceforge.net/project/graphicsmagick/graphicsmagick/1.3.16/...
?
I think it's safe to leave them, if you install the new version on /usr/local/*.
One more thing: when you do the installation of Koha there are some files that may have the wrong "shebang" line (#!/usr/bin/perl instead of #!/usr/local/bin/perl). Run (on /usr/share/koha) something like this # for i in $( egrep -Rl "/usr/bin/perl" * ); do perl -i -pne 's|\#\!\s*/usr/bin/perl|\#\!/usr/local/bin/perl|;' $i; done to fix them (there are a few files that are missed by fix-perl-path.PL) Bernardo
