gnucash fails on libgtkhtml

[Anthony Michael Agelastos]

Doing a

sudo port install gnucash

bombs on building gnucash with the error

checking for libgtkhtml-3.8 ... checking for libgtkhtml-3.6 ...  
checking for libgtkhtml-3.2 ... checking for libgtkhtml-3.1 ...  
configure: error: Could not find a working gtkhtml version (need 3.1,  
3.2, 3.6, or 3.8)

Further investigations showed

$ port installed | grep -i gtkhtml
   libgtkhtml @2.11.0_0 (active)
   libgtkhtml3 @3.14.0_0 (active)

It appears that gnucash is looking for an older version of libgtkhtml  
that is no longer available as a Port. Does anyone have any ideas?  
Thank you for your help.
