The output of emerge --info and build.log

libplist-2.2.0-r2 fails to build with the error:

    * ACCESS DENIED:  symlinkat:    /src/libplist.la
    ln: failed to create symbolic link '/src/libplist.la': Permission denied

As noted in the forums this looks like a bug in the ebuild:
https://forums.gentoo.org/viewtopic-p-8548458.html#8548458 

    src_compile() {
    #
    ln -s "${native_builddir}/src/libplist-2.0.la" "${native_builddir}/src/libplist.la"
    python_compile() {
        emake -C "${BUILD_DIR}"/cython \
            VPATH="${S}/cython:${native_builddir}/cython" \
            plist_la_LIBADD="${native_builddir}/src/libplist-2.0.la"
    }

    local native_builddir=${BUILD_DIR}
    [...]

where ${native_builddir} is used before it is defined so the symbolic link fails because it is pointing to the wrong location.

My emerge --info and build.log are attached.
Comment 1 Reid Swanson 2020-12-21 21:12:33 UTC 
For what it's worth, I created a modified ebuild in a local repo and moved the line:

    local native_builddir=${BUILD_DIR}

to the top of the src_compile() function and that appears to fix the issue for me. I've never really created a patch before so I'm not sure if I did it correctly, but I'll attach one of my fix. It's a pretty trivial change in any case.
