Hmm.. interesting.  We run on Squeeze 64 bit on our production machines.
Just going to check how we're building...

-g -fPIC -W -Wall -fstack-protector-all

Yep, but no PIE.  And that's probably because of the com_err stuff.

I'll try on my local box (Debian testing) and see what shakes out.
Yep, same issue.  Then this:

cc  -shared -O2 -g -L/usr/local/lib -fstack-protector IMAP.o  -o blib/arch/auto/Cyrus/IMAP/IMAP.so ../../lib/libcyrus.a ../../lib/libcyrus_min.a	\
	   -ldb-4.8 -lsasl2 -lz -lssl -lcrypto  	\
	  
/usr/bin/ld: ../../lib/libcyrus.a(imclient.o): relocation R_X86_64_PC32 against symbol `imclient_addcallback' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: Bad value

which looks to me like the -fPIC and friends aren't being passed down to
the Perl library generation.

I'd love patches to fix this.  I really don't know as much as I should about
this part of the process.
