How to fix MacPort’s version of w3m from crashing on Mac OS X 10.7 Lion

I like to use w3m command to display HTML content in emails under emacs.

I recently noticed some w3m instability after I upgraded to Mac OS X 10.7 Lion:

$ w3m
Segmentation fault: 11

Mac OS X also offered a helpful message of w3m quit unexpectedly and offered up a Problem Report that looked like this:

The above is pretty annoying, and after many Web Searches I found MacPort Ticket 30710.

Which explains that the current MacPorts version of boehmgc package isn’t Lion compatible.

Fortunately, the solution explained in the MacPorts ticket is simple, instead of the boehmgc package, use the newer boehmgc-devel package instead.

To make the switch I ran the following commands:

$ sudo port deactivate w3m boehmgc
--->  No broken files found.

$ sudo port install boehmgc-devel w3m 
--->  No broken files found.

And now w3m works well under Mac OS X 10.7 Lion.
