Yep, apparently by `sage-location`, during the build.
If I reinstall `libpng12`, and then MPL, everything is fine.
The offending line was
{{{
SAGE_ROOT=${SAGE_ROOT}
}}}
`SAGE_ROOT=/the/appropriate/absolute/path` works. I have no idea why `pkg-
config` doesn't take `$SAGE_ROOT` from the environment if it isn't defined
in the `.pc` file itself; it IMHO used to -- last year, but meanwhile
doesn't ... 8/
I.e.,
{{{
prefix=${SAGE_ROOT}
}}}
does no longer work unless `SAGE_ROOT` is also defined in the `.pc` file
itself.
We may have to really wrap `pkg-config` in `$SAGE_ROOT/local/bin` with
{{{
#!sh
#!/bin/sh
if [ -z "$SAGE_ROOT" ]; then
echo >&2 "Error: $0: SAGE_ROOT not defined."
exit 1
fi
exec /usr/bin/env PATH=`echo $PATH | sed -e "s|$SAGE_ROOT/local/bin:||"` \
pkg-config --define-variable=SAGE_ROOT="$SAGE_ROOT" "$@"
}}}
(Or just call the system's `pkg-config` ''without'' `--define-variable
...` if `SAGE_ROOT` is undefined.)
Defining `SAGE_ORIG_PATH` in `sage-env` wouldn't be a bad idea either.
