Sure:
atte@email-addr-hidden:~/software/zynjacku/zynjacku$ echo $LV2_PATH
/usr/lib/lv2:/usr/local/lib/lv2:/home/atte/.lv2

Seems like a good plan :-)

Nope, grabbed it from

First I got this:
atte@email-addr-hidden:~/software/zynjacku/zynjacku$ ./gen_py_constants.py
`pkg-config --variable=includedir lv2dynparamhost-1`
'^LV2DYNPARAM_PARAMETER_'
-bash: ./gen_py_constants.py: Permission denied

After making doing chmod +x I got:

atte@email-addr-hidden:~/software/zynjacku/zynjacku$ ./gen_py_constants.py
`pkg-config --variable=includedir lv2dynparamhost-1`
'^LV2DYNPARAM_PARAMETER_'
PyModule_AddObject(m, "LV2DYNPARAM_PARAMETER_TYPE_FLOAT_URI",

It's not even there. Note that I didn't run make in the zynjacku
directory before (should I?). Now I tried and got this:

Basically the first thing it complains is it's unable to find

As mentioned it wasn't executable but I changed that...

That sounds promising! Looking forward to getting it running!
