>Description:
The net/host package does not build on Solaris 05/09 x86 (pkgsrc current) and 
reports many errors. These are the root causes of the build failure :

1 - The package tries to build a static binary when it has always been such a 
pain on Solaris (there is no libc.a) 
2 - The sun linker does not kown about the --warn-common option.
3 - Some symbols are not defined in "regular" shared libraries. We have to add 
extra ones-lresolv -lsocket -lnsl to the linker in order to resolve all symbols.
4 - The andoc macro does not exist on Solaris 10 neither the ascii device type. 
This causes an error message when formatting man pages :
...
nroff -Tascii -mandoc host.1 > host.cat1
nroff: Cannot find library -mandoc
>How-To-Repeat:
build net/host on Solaris 10 (x86)
>Fix:
For problems 1, 2 and 3 I suggest to add this section in the Makefile :

.if ${OPSYS} == "SunOS"
LDFLAGS+= -lresolv -lsocket -lnsl
BUILDLINK_TRANSFORM+= rm:-Wl,--warn-common
BUILDLINK_TRANSFORM+= rm:-static
.endif

For the manpage formatting as a workaround one can use groff instead of the 
Sun's nroff (TOOLS_PLATFORM.nroff=/opt/pkg/bin/groff in mk.conf)
