hi,
the problem originates from fips_standalone_sha1.o, that seems to have
been compiled accidentally into libcrypto.so.2.2. this includes a main
symbol.

the fix is to remove this line:
SRCS+=3D fips_standalone_sha1.c
from lib/libcrypto/Makefile
and rebuild, reinstall libcrypto.

with this modification, darcs 1.0.3 builds for me under currentish.

thanks.
