I want to ensure I have the packages pst-pdf, auto-pst-pdf and pdfcrop.
I run tlmgr --gui and search for these and appear to install them.
However, if then do kpsewhich pst-pdf at the terminal it does not return the location etc. (only psfrag returns a location). Does this mean the packages are not installed? If not how do I install them and why is the GUI installation appearing to work but not.
