Hello,
as far as I understand, the systemwide libcom_err.a is non PIC, the
libcyrus_imap and libcyrus_sieve are PIC and it is not portable to
dymically link non-PIC libcom_err.a with PIC libcyrus_sieve . Yes, but
how to proceed in this case? Currently, Makefile.am states, that
libcyrus_imap depends on libcom_err, and when some application links
with libcyrus_imap, it automatically links with the system wide
libcom_err.a (implicit linking with shared libraries vs. explicit
linking when everything is statically built).
Does somebody know if it is portable to link the PIC executable (e.g.
imapd) with PIC libcyrus_sieve, and with non-PIC libcyrus_imap ?
Moreover, does it make any difference, if imapd links with
libcyrus_sieve and libcyrus_sieve links with libcom_err, or if imapd
links explicitly with both libcyrus_sieve and libcom_err ?

So what am I doing wrong,
Nothing.
or in the alternative what is the build system
doing wrong?
There is a path through configure.ac which sets
COM_ERR_LIBS="${with_com_err}/lib/libcom_err.a"
and COM_ERR_LIBS gets used to link against shared libraries in
Makefile.am
imap_libcyrus_imap_la_LIBADD = $(COM_ERR_LIBS) $(LIB_UUID)
...
sieve_libcyrus_sieve_la_LIBADD = $(COM_ERR_LIBS)

I would guess you did something like
./configure --with-com_err=/usr
but you should be able to get a better result by just dropping the
option entirely.
Ahh, yep - so I was! Looking better now :)
It's a bug; --with_com_err=/usr should be the same as no option. Raise
a bugzilla ticket.
