That works, thanks. I didn't think about the importance of the tex
file system structure within TEXMFHOME since my personal files
always have been picked up from random subdirectories within
TEXMFHOME.

mymodules/tex doesn't seem to be sufficient. My tests revealed that
for files not present in the distribution tex tree the location
within TEXMFHOME does not matter. Files present in the distribution
which are supposed to be overwritten in TEXMFHOME need the same
path. Maybe this is more strict than necessary, but it works. A
version mismatch that gets unnoticed can be very frustrating.

All right. Problem solved. Thanks Mojca!
