AntTweakBar Portfile addition

[karcaw@…]

Here is a port file for the AntTweakBar from here: ​http://www.antisphere.com/Wiki/tools:anttweakbar I have talked with Phillipe, and he is fine with me adding a port file, and maintaining it for him. I have built it in the graphics section for my testing.

Some things that should be changed:

• Setting distfiles explicitly is discouraged, as is hardcoding the name, version and extract.suffix in it. Try this instead:

  distname           ${name}_[join [split ${version} .] ""]
  

  That way, distfiles will automatically stay correct when version is changed.
• patch.pre_args defaults to -p0, so there's no need to set it to that.
• Instead of making a link to the extracted directory, just set worksrcdir like this:

  worksrcdir          ${name}
  

• The build system compiles with 'gcc'. This could point to any gcc version, so for consistency, it should be made to use the value of ${configure.cc} instead.
• It also passes -I/usr/local/include -I/usr/X11R6/include to the compiler. Ports should not normally use anything from these locations, and problems can result if conflicting headers are installed there.
• Regarding the patch, $(PREFIX) starts with a slash, so $(DESTDIR)/$(PREFIX) ends up having a double slash.
