This seems strange. The file `installed/eclib*` is missing and according
to `deps`, it's required for the `sage` target. Similarly,
`installed/sage*` is a prerequisite for gap. Does anyone know why this
happens? Can we modify `deps` to avoid it?
The problem is that the exit status `$?` of
{{{
#!sh
$(SAGE_SPKG) $(FOO) 2>&1 | tee -a $(SAGE_LOGS)/$(FOO).log
}}}
is the exit status of `tee`, but we need the exit status of `sage-spkg`.
(I found some other workarounds [http://www.unix.com/shell-programming-
scripting/92163-command-does-not-return-exit-status-due-tee.html here].)
We can get this with `$PIPESTATUS` in `bash`. We could add a helper
script somewhere that runs the pipeline and exits with the status of
`sage-spkg`.
Or we could use
{{{
#!sh
$(SAGE_SPKG) $(FOO) 2>&1 | tee -a $(SAGE_LOGS)/$(FOO).log | grep "sage: An
error occurred while"
}}}
if we test the status of `grep`. The `sage-spkg` script prints this error
string when `spkg-install` or `spkg-check` fails. We could also print
the string in a few other places in `sage-spkg` (search for `exit 1`).
Thoughts?
