Probably a "#include <signal.h>" is missing, if these are the only signals
being trapped.  If not, then its possible (very unlikely though) that these
signals are not in your /usr/include/signal.h. (it's either <signal.h> or
<sys/signal.h>, can't remember which).

Yes exactly.  Assuming that crypt() is defined in libcrypt (you can confirm
this using "nm libcrypt.a | grep crypt", if nm is available on linux, damn i
wish i was home), it looks as though libcrypt is not part of the list of
objects/libs being linked by gcc.  The gcc line should include a -lcrypt as
shown below.

gcc -g -O2  -o cyrus-imspd main.o dispatch.o imsp_server.o option.o
syncdb.o adate.o bb.o im_util.o imap_client.o abook.o authize.o alock.o
login_unix_shadow.o proxy_unix_shadow.o ../lib/libcyrus.a  
-lresolv -ldb-lndbm -lcrypt

Since you're probably running this from a makefile, look for -lndbm and add
-lcrypt to the line.  (Alternatively you could also give "<path>/libcrypt.a"
instead.)

Good Luck.
