Compiling scala files inside their package folder from Command Line

I am trying to compile scala files from INSIDE their package folders. So I have three files, Patient.scala, PatientMonitor.scala, and VitalSigns.scala, they all reside in the following path gasguru/patient/

Here is my file VitalSigns.scala

// /gasguru/patient/VitalSigns.scala
package gasguru.patient
  class VitalSigns () {
      var heartRate = 0;
  }

and I compile it with the following line: scalac -d ../.. VitalSigns.scala this results in the VitalSigns.class file being created in the same directory as I am currently in.

Now if I go to compile Patient.scala which contains this: 

// /gasguru/patient/Patient.scala
import gasguru.patient.VitalSigns;
package gasguru.patient {

  class Patient ( val firstName:String, val lastName:String) {
    val vitalSigns = new VitalSigns();
  }
}

and if I try and compile it with this following line: scalac -d ../.. Patient.scala I get the following error 

Patient.scala:2: error: VitalSigns is not a member of gasguru.patient
import gasguru.patient.VitalSigns;
       ^
error: error while loading VitalSigns, Missing dependency 'class gasguru.patient.VitalSigns', required by ./VitalSigns.class
Patient.scala:6: error: VitalSigns does not have a constructor
        val vitalSigns = new VitalSigns();  
                                 ^
three errors found

Why am I getting this error when the VitalSigns.class resides inside of the same directory as where I am compiling the file? Shouldn't importing it suffice?

Thanks!

EDIT: 

chs@ubuntu:~/GasGuru/gasguru/patient$ ls
exceptions            Patient.scala     VitalSigns.scala
PatientMonitor.scala  VitalSigns.class

You are not passing the source file of VitalSigns.scala as a parameter, so it will try to search for a classfile. The classfile of a class in the package x.y is under the directory x/y, which means it is trying to find gasguru/patient/VitalSigns.class, which does not exist in the current directory you are at.

If you add -classpath ../.., it should find the file.
