I have no idea.

This is a little bit complicated. Opensc is a driver for smartcards, 
openct is a driver for smartcard readers and security/pcsc-lite is a 
middleware to access smartcard readers via SCard API. Pcsc-lite is used 
normally together with security/ccid driver for smartcard readers 
conforming to CCID and ICCD specifications.

For majority of users it's sufficient to use pcsc-lite and ccid with 
opensc. This combination doesn't cover all use cases though. For example 
for cmx(4) PCMCIA reader I use in most of cases, openct is needed. Openct 
can used either directly by opensc or it can be compiled with pcsc-lite 
support - ie. readers supported by opnect (I'm not sure whether all of 
them though) can be used via pcsc-lite (via special handler).

So I made defaults reasonable which should cover most of cases:

app --> opensc --> pcsc-lite --> ccid
                           \
                             --> openct

But if someone wants to rule out pcsc-lite for whatever reason, he/she has 
the way - to compile opensc to use openct directly:

app --> opensc --> openct


I hope this clarifies things a little bit ;).
