[BioC] EBImage install problems

[Wolfgang Huber]

Hi Crispin,

- The libmagick9-dev package contains header files (e.g. filename.h) for 
the libmagick9 library. AfaIk it does not contain executable code. It is 
necessary for compiling other programs that want to use functions or 
other symbols from libmagick9. From your description, it appears as if 
the header files are present, and found by R CMD INSTALL, on your system.

- However, it seems that the loader does not find certain shared library 
files. Did you set LD_LIBRARY_PATH to include the location of where you 
installed the libmagick9 object files?

  Best wishes
	Wolfgang
