Sorry to hear this. We have a lot of connections with the high energy physics community, which is why ROOT and Gaudi are even in Spack to begin with. There is an #hep channel on https://slack.spack.io, and we talk to those folks fairly frequently to figure out what we can add to support these codes better.
On `LD_LIBRARY_PATH` specifically: we intentionally inject RPATH-ing compiler wrappers into the build to avoid these types of problems, which are on by default for the ROOT and Gaudi builds. Would be curious to hear where the remaining pain points are.
