AntTweakBar: dylib has wrong install_name

[ryandesign (Ryan Carsten Schmidt)]

The dylib installed by AntTweakBar has a slightly wrong install_name:

$ port contents AntTweakBar
Port AntTweakBar contains:
  /opt/local/include/AntTweakBar.h
  /opt/local/lib/libAntTweakBar.dylib
$ otool -L /opt/local/lib/libAntTweakBar.dylib
/opt/local/lib/libAntTweakBar.dylib:
	//opt/local/lib/libAntTweakBar.dylib (compatibility version 0.0.0, current version 0.0.0)
	/System/Library/Frameworks/OpenGL.framework/Versions/A/OpenGL (compatibility version 1.0.0, current version 1.0.0)
	/System/Library/Frameworks/GLUT.framework/Versions/A/GLUT (compatibility version 1.0.0, current version 1.0.0)
	/System/Library/Frameworks/AppKit.framework/Versions/C/AppKit (compatibility version 45.0.0, current version 1038.35.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.10)
	/usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current version 227.0.0)
	/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 550.42.0)
	/System/Library/Frameworks/Foundation.framework/Versions/C/Foundation (compatibility version 300.0.0, current version 751.53.0)

Note how its name begins with two slashes. The attached patch fixes this. May I commit it?
