based on the removal of glist_findrtext in the following commit part, pdlua won't properly load in upcoming Pd versions anymore:
pure-data/pure-data@1b928e6#diff-e0f324f94ffa2e22b8c83c57e7d1c7002c0859c9a5960e4013dd7434e1dbff9cL478

(learnt about this now: git log -S glist_findrtext --oneline src/g_canvas.h)

with a build from Pd's current master branch, i get:

/path/to/pdlua/pdlua.pd_darwin:dlopen(/path/to/pdlua/pdlua.pd_darwin, 0x000A): symbol not found in flat namespace '_glist_findrtext'

there is glist_getrtext with identical interface though now ...
