I think there is a scenario where Lorinc would be completely innocent:
Install fink from the latest binary installer;
then update dpkg from binary
-> Fatal crash!
I just tried it, it "works", at least on ppc; on intel, it crashes
before the new dpkg gets installed, because a dependency is missing.
Here are the three simple commands I ran as root:
installer -pkg /Volumes/Fink-0.8.1-PowerPC-Installer/Fink\
0.8.1-PowerPC\ Installer.pkg/ -target /
apt-get update
apt-get install dpkg
The last command crashes as follows:
Preparing to replace dpkg 1.10.21-1218 (using
.../dpkg_1.10.21-1219_darwin-powerpc.deb) ...
Unpacking replacement dpkg ...
dyld: Library not loaded: /sw/lib/libiconv.2.dylib
Referenced from: /sw/bin/dpkg
Reason: Incompatible library version: dpkg requires version 6.0.0 or
later, but libiconv.2.dylib provides version 5.0.0
E: Sub-process /sw/bin/dpkg exited unexpectedly
And from then on the new Fink installation is fatally hosed :-(
What happens is that the binary installer has dpkg-1.10.21-1218 which is
linked with libiconv-1.9.1-11 which has compatibility version 5.0.0.
The binary repository, however, has also dpkg-1.10.21-1219 (in its
"current" tree), and this revision is linked to a libiconv.dylib of
compat version 6.0.0, which itself would be provided by the
libiconv-1.10.6 package, also available from the "current" bindist.
Now dpkg's dependency on libiconv is unversioned, so that it is
perfectly possible to apt-get update; apt-get install dpkg without first
updating libiconv.
This looks to me like a serious bug, and I am therefore CCing devel.
BTW, on intel this cannot happen, because one gets instead:
Sorry, but the following packages have unmet dependencies:
dpkg: Depends: libgettext3-shlibs but it is not installable.
Indeed, the dependency libgettext3-shlibs is not present in the bindist,
so that dpkg cannot be upgraded to its latest version in the bindist.
This is less fatal than what happens on ppc, but it doesn't look right
either.
