Uhm, Gentoo is a source distribution. The outcome of a package  
installation can depend on many things, such as used compiler,  
enabled/disabled features for the package and compiler/linker flags.
That said, I am currently maintaining this ebuild (package  
information/installation file):  
It is a continuation of the abandoned "d-overlay" ebuild and the dmd.conf  
generation code originates from there. On a positive note, Ubuntu recently  
had a problem with dmd when they switched to --as-needed, that does not  
occur with the Gentoo ebuild, since --as-needed was already in use there  
for a while.
Since I am not an expert with Gentoo ebuilds or executable linking, I did  
not change the ebuild much and it works for me. The stack traces are in  
deed the reason for --export-dynamic. If there is anything that should be  
resolved in dmd.conf for Gentoo, instead of the compiler itself, then I am  
the one to bug.

Installation goes like this (assuming layman has been installed):

1. Add official external repository for wannabe packages:
layman -a sunrise

2. Install latest dmd (needs to be unmasked in  
/etc/portage/package.keywords first):
emerge dmd
