aubio @0.4.1: undefined symbols

[ryandesign (Ryan Carsten Schmidt)]

I have aubio @0.3.2_4 installed, but it doesn't want to upgrade to @0.4.1 for me:

Deactivating aubio @0.3.2 first allowed @0.4.1 to build. So one possible solution would be to use

PortGroup conflicts_build 1.0

and

conflicts_build ${name}

[dbevans (David B. Evans)]

By placing LDFLAGS before other link flags on the link command line, waf causes previously installed versions of the aubio libraries to be linked in preference to the new local ones. Deleting -L${prefix}/lib from LDFLAGS fixes the problem. External libraries that need to be linked assert their library search paths via pkg-config and are not effected.
