Hello Wolfgang, at first thank you once again for your effort. The day before yesterday I tried to compile seamonkey from source with German language support. I compiled seamonkey successful a few time before but this was my first non English version. Here my experiences: Operating system Slacko 700 RC3 K4.4.70 PAE ( Slackware 14.2 basing Distribution ) seamonkey-2.49.3.source.tar.bz2 de-SEAMONKEY_2_49_3_RELEASE.tar.bz2 The compilation process went without problems but the installer aborted installation with following error message. Error: /root/SM-2.49.3-SOURCE/seamonkey-2.49.3/obj-i686-pc-linux-gnu/suite/installer/package-manifest:40: Missing file(s): bin/dictionaries/* Traceback (most recent call last): File "/root/SM-2.49.3-SOURCE/seamonkey-2.49.3/mozilla/toolkit/mozapps/installer/packager.py", line 415, in <module> main() File "/root/SM-2.49.3-SOURCE/seamonkey-2.49.3/mozilla/toolkit/mozapps/installer/packager.py", line 367, in main copier.add(mozpath.join(respath, 'removed-files'), removals) File "/usr/lib/python2.7/contextlib.py", line 24, in __exit__ self.gen.next() File "/root/SM-2.49.3-SOURCE/seamonkey-2.49.3/mozilla/python/mozbuild/mozpack/errors.py", line 131, in accumulate raise AccumulatedErrors() mozpack.errors.AccumulatedErrors /root/SM-2.49.3-SOURCE/seamonkey-2.49.3/mozilla/toolkit/mozapps/installer/packager.mk:41: recipe for target 'stage-package' failed make[2]: *** [stage-package] Error 1 make[2]: Leaving directory '/root/SM-2.49.3-SOURCE/seamonkey-2.49.3/obj-i686-pc-linux-gnu/suite/installer' /root/SM-2.49.3-SOURCE/seamonkey-2.49.3/mozilla/../suite/build.mk:16: recipe for target 'install' failed make[1]: *** [install] Error 2 make[1]: Leaving directory '/root/SM-2.49.3-SOURCE/seamonkey-2.49.3/obj-i686-pc-linux-gnu' client.mk:404: recipe for target 'install' failed make: *** [install] Error 2 # Seamonkey and the language package doesn't contain dictionaries folder and dictionaries but it seems that installer is looking for it and aborted installation if not present. So I edited the manifest and commented the "dictionaries" line out [@AB_CD@] @RESPATH@/chrome/@AB_CD@@JAREXT@ @RESPATH@/chrome/@AB_CD@.manifest @RESPATH@/defaults/messenger/mailViews.dat @RESPATH@/defaults/profile/bookmarks.html @RESPATH@/defaults/profile/chrome/* @RESPATH@/defaults/profile/mimeTypes.rdf @RESPATH@/defaults/profile/panels.rdf ; @RESPATH@/dictionaries/* @RESPATH@/hyphenation/* Now intallation went without problems. I don't know whether this is the reason in your case too. Best greetings Norman
