But only twice... I get it listed thrice in my plugin...
strings /usr/local/CoolVLViewer-1.26.21/bin/llplugin/media_plugin_cef.so |
grep _ZN8dullahan26setOnStatusMessageCallback
_ZN8dullahan26setOnStatusMessageCallbackEN5boost8functionIFvSsEEE
_ZN8dullahan26setOnStatusMessageCallbackEN5boost8functionIFvSsEEE
_ZN8dullahan26setOnStatusMessageCallbackEN5boost8functionIFvSsEEE

(there's "boost" because I "re-boostified" Dullhan's interface for
C++98 compatibility).

So, it looks indeed like a linking issue even though:

Using the same versions here, for personal builds, with no issue
whatsoever.
