Bo,I am sorry for pushing you all the time.... scons still does not install LyX properly:
Install file: "/home/software/lyx-trunk/po/wa.gmo" as "home/software/lyx-bin/share/locale/wa/LC_MESSAGES/lyx.mo"
As you can see, the leading '/' is stripped from the prefix, which means that all files are installed in ..../development/scons/home/... :-(
Both 1.4.X and 1.5.0, of course. Michael
