opendx: parallel build issue: tmp.c: No such file or directory

have error when install opendx on lion system as following:

None of that shows us the actual error that occurred. Please attach the complete main.log file.

Your log says:

That looks like a parallel build failure. Try turning off parallel building:

sudo port clean opendx
sudo port install opendx build.jobs=1

Did disabling parallel building (as shown above) help?

[ryandesign (Ryan Carsten Schmidt)]

I couldn't reproduce the problem after several tries, but parallel build issues can be notoriously difficult to reproduce. I also don't have the 4 CPU cores you appear to have, nor Lion at the moment.

Based on your log and the Makefile code, it sure looks like there could be a parallel build issue. I tried to fix it in r86601. It (still) builds for me.
