GraphDef_Recv error with source built sc3-plugins

[heretogo]

Version Info

SuperCollider version: 3.15.0-dev (Built from branch 'develop' [21347a84c])
sc3-plugins version: 2db38c7

Description

I'm building everything from source on Debian Trixie.

sc3-plugins build and install with no errors to /usr/local/share/SuperCollider/Extensions/SC3plugins

However, when I try to load a UGen, say LorenzTrig, I get the following:

-> Synth('temp__0' : 1000)
exception in GraphDef_Recv: UGen 'LorenzTrig' not installed.
*** ERROR: SynthDef temp__0 not found
FAILURE IN SERVER /s_new SynthDef not found

Any ideas?

supercollider/supercollider@a27ec6c introduced a breaking change in the plugin API.
Can you make sure that you have built sc3-plugins using the matching plugin API version of your running SC instance? E.g. during booting there should be a warning if the plugin api version is not matching.

That's interesting. I do not receive an error about the plugin api version and my SC build (21347a84c) predates the commit you mentioned.
