Allora il percorso non è $TEXMFHOME? Quello suggerito da te mi restituisce /usr/local/share/texmf invece $TEXMFHOME mi da /home/spike/texmf!
A parte questo nel log si vede che qualcosa viene caricato dalla cartella giusta, mentre una miriade di altri (credo) sottopacchetti di pgf vengono presi dalla /usr/share/texmf.
A questo punto dovrei prendere uno per uno quei pacchetti e inserirli nella versione aggiornata in $TEXMFHOME (o LOCAL)? Ci uscirei pazzo!!! Riporto di nuovo la parte di log relativa al pacchetto così si capisce meglio:
