What happens if you run pdflatex from a different directory and give it the path to the exported .tex file? LyX does not run pdflatex in the source directory; it exports the .tex file to a temp directory, copies over image files (mangling their names as needed) and compiles in the temp directory, so as not to screw up anything in the source directory. It should be copying over the PDF files, but it has no way of knowing that it needs to copy over the TFM files. If the TFM files are on the LaTeX search path, then no copying of them should be required (pdflatex should be able to find them from anywhere). Paul
