librsvg @2.42.2_0: build fails

[mndavidoff (Monte Davidoff)]

I get the following error when I try to install librsvg:

sudo port -vs install librsvg

I recently updated to macOS 10.13.4 and Xcode 9.3 in case the problem is related to that.

Appears to be the result of recent universal build changes in bcd0bba54c18b9c504e185d9f3e168b1bb54e5b7/macports-ports that manipulate environment variable CARGO_BUILD_TARGET.

The non-universal build is attempying to link to static library

${worksrcpath}/rust/target/release/librsvg_internals.a

but the actual path to the built library is

${worksrcpath}/rust/target/x86_64-apple-darwin/release/librsvg_internals.a

As a quick and dirty hack, you can setup a symlink and then re-trigger the build as a workaround:

    dports/graphics/librsvg/work/librsvg-2.42.2/rust/target/release $ sudo ln -s ../x86_64-apple-darwin/release/librsvg_internals.a

In f31dfa307208536530722a4364bdc41983863837/macports-ports:

librsvg: patch configure.ac when using autoreconf

Using one patchfile for both configure and configure.ac yields:

WARNING: 'aclocal-1.15' is missing on your system.
make: * [aclocal.m4] Error 127

No revbump since port either builds correctly or not at all

Fixes #56192
