Thanks for taking a look at it. Yes, the spkg-install is modified:

+find . -type f -exec sed -e 's@/bin/cp@cp@g' -i '{}' ';'
+sed -e 's@yylex (&yylval)@yylex (\&yyval, scanner)@gp' 'input_parser.cc'
if [ "$SAGE_LOCAL" = "" ]; then
echo "SAGE_LOCAL undefined ... exiting";
```
The first line is nixos specific (cp is not in /bin). The second was my
attempt to fix it, but I
got the path of `input_parcer.cc` wrong (which is why sed couldn't find the
file). I'm currently
running a build with the path corrected.
