However, I could not use a Postscript version of my picture (I use a PNG instead). In the document window I get an error message that it can not be converted, and when I try to convert to a PDF, I get a notice that ghostscript crashed because a library could not be found (libXt.6.dylib). I'm writing this because in the text of section 5.4 it says that the graphics package is needed to display Postscript, so the installation looks incomplete. Now I just re-installed the whole teTeX package. The installer did not need additional space (indicating to me that all packages were already in place), but now at least gs finds its library. The picture still can't be displayed in LyX, though, and all error messages stay unchanged! What can I do now?
First, make sure that you have ImageMagick installed. I do not think this is the source of the error messages, but it cannot hurt to check.
Second, what happens if you insert a graphic directly into a document (without using a float)? You might try inserting one of your image files into a new document to test. Do you still get the error message?
Third, when you get an error message, the LaTeX log file should indicate where the error occurred. Just above the first "undefined control sequence" line should be a portion of a source line, indicating what it was that LaTeX thought was an undefined control sequence. Please post that.
