pdf export errors

Hello.

I am trying to do some simple drawings and export them as pdfs so I can import them to a laser cutter. However I am getting two types of error and having looked through the forum cant find a simple answers:
Error 1 -

When I use "import processing.pdf.*;" at the start of the sketch I get :

More than one Library is competing for this sketch...
pdf (part of processing)

Extra Librarys need to be removed before ths sketch can be used.

By which I infer that the PDF library is now part of the central core of Processing so I do need this line at the start... OK so...

Error 2 -

 When I remove the offending  line I get: the following tirade which I believe means - put it back

Exception in thread "Animation Thread" java.lang.RuntimeException: You need to use "Import Library" to add processing.pdf.PGraphicsPDF to your sketch.

    at processing.core.PApplet.run(PApplet.java:2140)
    at java.lang.Thread.run(Thread.java:680)

I am confused. I assume I am doing this wrong? but the reference say do it this way.?

Any help would be much appreciated.

Regards
