games/wesnoth: How to cope with "invalid DSO for symbol `_ZN5boost6system15system_categoryEv'"

[Torsten Zuehlsdorff]

Hello,

i'm currently working on an update for games/wesnoth. I've made good 
progress and the game compiles with nearly all options at my 8 year old 
i386 Laptop with 10.0-RELEASE.

But when i try compiling it on my fast amd64 10.1-RELEASE i get this 
error message:

=== end ===

As you can see my devel/boost-libs is the current version. After some 
searching i believe their is nothing i can done, other than reporting 
this to the project? But why does it work at my laptop - the installed 
boost-libs (and all other ports and their options) are (or at least 
should be) identical.

Am i right? Or are their options or flags for boost-libs, ld or another 
invoked program which i should try?

Thank you very much,
Torsten
