sed error when installing swig

[jjstickel@…]

I get the following when trying to install swig:

sudo port -ud upgrade swig
...

Looks like the reinplace line of the Portfile needs work.

Thanks, Jonathan

WFM. /usr/local/bin/sed is unsupported.

[ryandesign (Ryan Carsten Schmidt)]

Right. Please remove /usr/local/bin/sed and ideally anything else you have in /usr/local, clean the affected port (i.e. "sudo port clean swig") and try again.

My apologies. I kept a convenience symlink /usr/local/bin/sed -> /opt/local/bin/gsed which apparently caused a problem here.
