I selected the personal desktop installation class and choosed to select the packages myself. I didn't included any development packages ( GNOME/KDE/kernel development ), but after install rpm -qa | grep devel shows the devel versions of glibc, XFree86, gimp and gtk+.
Are you sure you didn't inadvertantly select a package(s) which have a dep on a devel package? The reason I ask is because anaconda will auto-resolve deps and install the needed packages. Tim
I didn't go into manual selection of every package screen, just chosen the categories. If I didn't choose GNOME Development, I shouldn't have gtk+ and gimp devel. Perhaps there's a depency in the rest of the packages which shouldn't be there. Not a big deal, but I thought it worths mentioning.
This should be fixed internally now. The problem was that xsane-gimp was needing /usr/bin/gimp-config, which started the -devel package suckage. Tim
