Hi,
I don't know if this is already fixed in the latest version; I downloaded an autobuild of Pd Extended 0.42.5 for Ubuntu a few months or weeks ago, and now when looking for the Gem examples that I couldn't find, I found out that in
/usr/lib/pd-extended/doc/examples
there's a broken link that points to
/home/pd/auto-build/pd-extended/packages/linux_make/build//usr/lib/pd-extended/extra/Gem/examples
instead of just
/usr/lib/pd-extended/extra/Gem/examples
Just thought I'd let you know in case this isn't already known
bye m.
