Exactly this. DragonFly has moved to the latest release of binutils recently, 
which changed default behaviour regarding automatic linking of dependencies. In 
practice this means that all static libraries a program needs must be linked in 
explicitly, even if another library uses them. The "correct" fix is to add a 
configure check for libm.


This is not technically a DragonFly problem, sooner or later other systems will 
have the same problem; there's just a ton of packages out there that need 
fixing.
