Serghei, Could you offer any suggestions as to why arts cannot be found during the kdelibs build process? http://quickbuild.pearsoncomputing.net:58080/2051543/buildlog_ubuntu-maverick-i386.kdelibs-trinity_4%3A3.5.12-0ubuntu7%2Br1224234%2Bpr45_FAILEDTOBUILD.txt.gz I wonder if it may have anything to do with moving the two main arts header files from include/arts/arts*.h to include/artsc/arts*.h Thanks!
