Yes, it can. Anyone can contribute updates to the documentation by submitting a pull \
request. Much of the Guide has not been updated in over a decade and is in dire need \
of rewrites or replacement.

MacPorts will print a message saying Xcode is required to install that port.

"port search" does not do a search of the entire literal contents of portfiles, but \
you can use grep to do that.
Ports that include the xcode portgroup also most probably require Xcode. I would have \
thought that the xcode 1.0 portgroup would declare "use_xcode yes" somewhere in it, \
but it doesn't seem to. Maybe that is an oversight.
According to this:
port file all | sort -u | xargs grep -El \
'^[[:space:]]*(use_xcode[[:space:]]yes|PortGroup[[:space:]]+xcode[[:space:]])' | wc \
-l
there are around 180 ports that require Xcode. There may be others that require Xcode \
but that do not so indicate yet.
