Sorry yes, I used poor phrasing of words. Not monolithic.
Static in terms of our internal libraries.

Building MusE with --no-undefined requires our
  DMODULES_BUILD_STATIC flag.

MusE normally builds shared modules which all depend on each other.
--no-undefined doesn't jive with that concept.
It is asking for hard dependency links when they haven't even
  been built yet.

IIUC --allow-shlib-undefined is the default and the reasons
  given are exactly the reasons why MusE needs it.

It seems --as-needed may not produce the same results.
One submitted terminal output showed it mistook fluidsynth's
  event.h for our event.h
I can only assume that was the reason, because there's no trouble
  building MusE from source with default flags.

So...
Packager's choice then: 'Normal' build, or if you want
  --no-undefined then you need DMODULES_BUILD_STATIC.

However, I am seeing issues with our DMODULES_BUILD_STATIC.
As I mentioned, there are a few dependencies of Arranger on the core.
I can straighten that out easily.

What is /not/ so easy to straighten out are our MESS plugins.
Our MESS plugins always build as shared libraries (they are plugins
  like any other plugin system.)
If you give --no-undefined and DMODULES_BUILD_STATIC, the main app
  will build OK (given my pending fix of Arranger dependencies)
  but the MESS plugins have several dependencies on the core module.
It is a bit of a... mess if you'll excuse the pun.
The plugins were supposed be independent and stand-alone.
But currently they need the core and a couple of other modules.

So I'll try to straighten that out so that --no-undefined
  can be used if desired.
