Comment (by Polyergic):

 I was trying to follow the first suggestion in comment 4, which says
 installing the `-devel` package will satisfy the dependency.  It doesn't.

 The suggestion in comment 5 also doesn't work.  Errors include this:
 {{{

 :info:build            ^
 }}}

 The second suggestion in comment 4 seems to have worked.  Do I understand
 right that if that fix is included in the next update I won't have to do
 this again myself?
