Build sets a wrong id path for dynalic library

[barracuda156]

Apparently the id is set wrongly by the build:

36-209% otool -L /opt/local/lib/libbasiclu.2.2.0.dylib 
/opt/local/lib/libbasiclu.2.2.0.dylib:
	lib/libbasiclu.2.2.0.dylib (compatibility version 2.0.0, current version 2.2.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 117.0.0)
	/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)

It leaves dependents broken, since nothing is found at lib/libbasiclu.2.2.0.dylib.
