There is an adapter.  See 
http://www.aeolusdevelopment.com/Articles/InSystemProgramming.html

It contains the necessary level convertors and (program controlled) 
pull-downs and connects to a standard ISP header.  It works with all three 
of the publicly available serial ISP programs I know of and uses the 
automatic reset/ISP mode pins.  There's also an isolated version.

The standard ISP header takes up rather less room than the D-sub + level 
converters. So it will save you room and cost if you are doing more than a 
couple of boards.

Having said that for the Philips evaluation board a Dsub to Dsub cable may 
make more sense.  Especially if they have an easy way to switch to/from 
programming mode.  It would also be fairly simple to wire the ISP header 
into the prototyping area.
