Is this really true?  What happens if, say, your program depends on
PCRE, which has different sonames on Debian/Ubuntu and Fedora (for
essentially the same library):

fedora$ rpm -qf /usr/lib64/libpcre.so.0
pcre-8.21-2.fc17.1.x86_64

ubuntu$ dpkg -S /lib/x86_64-linux-gnu/libpcre.so.3.12.1
libpcre3: /lib/x86_64-linux-gnu/libpcre.so.3.12.1
ubuntu$ dpkg -l libpcre3-dev
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name           Version        Description
+++-==============-==============-============================================
ii  libpcre3-dev   8.12-3ubuntu2  Perl 5 Compatible Regular Expression Library

I don't understand how a binary built on one platform could be copied
across to the other and work.
