Comment (by kencu):

 Although you are completely correct in pointing out the libuv @1.10.1 does
 not build on Tiger (at least at this moment -- these things usually have a
 way of working out in the end), I might guess that the reason you now need
 libuv is because of the change in cmake-3.7.1; the portfile now specifies
 the system-library versions of most libraries, one of which is libuv.

 Cmake also includes it's own versions of the needed system libraries,
 however, and these internal versions still build on Tiger (go figure).

 So one way around your libuv issue is to edit the cmake portflle, remove
 the requirement for libuv by commenting it out like this:
 {{{
 #depends_lib-append  path:lib/pkgconfig/libuv.pc:libuv
 }}}

 and change the following configure arguments from this:
 {{{
 --init=${worksrcpath}/macports.cmake \
 --system-libs \
  --no-system-jsoncpp
 }}}
 to this
 {{{
 --init=${worksrcpath}/macports.cmake
 }}}

 then, when upgrading cmake, the system libuv is not required, and cmake
 3.7.1 builds through to completion on Tiger without trouble.

 {{{
 $ port -v installed | grep cmake
  cmake @3.6.3_0 platform='darwin 8' archs='ppc'
  cmake @3.7.1_0 (active) platform='darwin 8' archs='ppc'
 }}}

 if you actually needed libuv for some other reason besides cmake - well,
 obviously this won't help you.  K.
