If you don't mind errors when you attempt to apply the manifest and the
homedir does not exist, then you could make the authorized_keys file
depend on something that fails if the homedir does not exist.
Here's an untested example:
# If the directory exists, then the "unless" clause in the exec
# is satisfied, so the "command" does not run; but the overall
# exec resource behaves as if it was successful, and anything that
# requires this exec is happy.
#
# If the directory does not exist, then the "unless" fails, so the
# "command" runs; but the command is "/bin/false", so the command
# reports a failure, the overall exec resource fails, and anything
# that requires this exec will have a failed dependency and will
# therefore not be evaluated.
#
exec { "fail if $homedir does not exist":
command => "/bin/false",
unless => "/usr/bin/test -d $homedir",
}
file { "$homedir/.ssh/authorized_keys":
source => "puppet:///wherever",
require => Exec["fail if $homedir does not exist"],
}
