Hi,

ircd-hybrid fails to build from source due to a missing build-dependency on
libcrypt-dev. Logs follow.

/usr/bin/x86_64-linux-gnu-ld.bfd: conf.o: in function `match_conf_password':
./src/./src/conf.c:1404:(.text+0x1685): undefined reference to `crypt'
collect2: error: ld returned 1 exit status
make[3]: *** [Makefile:607: ircd] Error 1
