[OS X TeX] blackboard bold semicolon

I am trying to produce a blackboard bold semicolon.  My test file is  
as follows:


$R{\mathbb{;}}S$ and $R;S$ should look different (the semicolon should
be blackboard bold and normal, respectively).  Also, look at
$\mathbb{R;S}$ and $R;S$ the complete math expressions should be
blackboard bold and normal, respectively).

Following the advice in the "Comprehensive LaTeX Symbol List", I have  
tried this using the amsfonts, amssymb, txfonts, pxfonts, mathbbol,  
bbm, and dsfont packages (with the variant versions of the \mathbb  
command).  I didn't try the bbol or mbboard packages, since they are  
not installed.

None of these produced a blackboard bold semicolon---just the normal  

Note that the blackboard bold semicolon showed up ok in "tex  
testfont", using bbold10 (or bbold17) as the test font.

Any idea what I'm doing wrong here?  Thanks.
