Ports that install binaries

[Ryan Schmidt]

I'll continue this discussion on the dev list, where I probably  
should have started it in the first place.

True... Thanks... I guess what I should have asked is if there were  
any ports that download disk images and install their contents, since  
that's a bit more complicated. I know MacPorts knows how to extract  
files from .tar.gz and .tar.bz2 archives, but I'm wondering if  
there's anything in place for .dmg files.

Grepping all portfiles for "dmg" I only see one -- abiword -- which  
lets you choose either to compile from source or install a binary  
from a disk image. For the latter, it looks like this:


variant use_binary conflicts use_source {
	distname AbiWord-${version}-10.2
	extract.suffix .dmg.gz
	master_sites    http://www.abisource.org/downloads/abiword/$ 
{version}/MacOSX
	checksums	md5 13d249d7f0181a5c44e7342b302b19ae
	use_bzip2	no
	extract.post_args > ${workpath}/${distname}.dmg
	post-extract {
		file mkdir /tmp/${name}-${version}
		system "hdiutil attach ${workpath}/${distname}.dmg -private - 
nobrowse -mountpoint /tmp/${name}-${version}"
	}
	patch {}
	use_configure	no
	build {}
	destroot {
		file mkdir ${destroot}/Applications/MacPorts
		file copy /tmp/${name}-${version}/AbiWord.app ${destroot}/ 
Applications/MacPorts
	}
	post-destroot {
		system "hdiutil detach /tmp/${name}-${version}"
		file delete -force /tmp/${name}-${version}
	}
}


So it calls hdiutil directly. Is that how I should do it? Or are  
there any built-in MacPorts commands for dealing with disk image  
distributions?
