I'm trying to package Thunderbird but run into an issue since 21b1. I do basically a make -f client.mk build cd ../obj make -C mail/installer which always worked correctly. With 21.0b1 it fails during running precompile_cache when executing xpcshell because the libraries are not found. Followed that back to gre_path (which is used to set up LD_LIBRARY_PATH) is set to bin/chrome instead of just bin/ in toolkits' packager.py I couldn't find the reason for that yet.
still the same with 24pre
Are you building with enigmail?
I do indeed.
