Imagemagick, no decode delegate for this image format `JPEG'

Hi puppybyte!
If you run:

--- Code: ---identify -list format
--- End code ---
Do you get any response?

Hide the policy file:

--- Code: ---sudo mv /usr/local/etc/ImageMagick-7/policy.xml /usr/local/etc/ImageMagick-7/policy.xml.off
--- End code ---
See if the convert command works then.

1.  no response to identify -list format
2.  I hid the policy file
3.  convert command with same result.

--- Code: ---tc@box:~/pictures/P4$ convert sample.jpg -rotate 5 out.jpg
convert: no decode delegate for this image format `JPEG' @ error/constitute.c/ReadImage/562.
convert: no images defined `out.jpg' @ error/convert.c/ConvertImageCommand/3273.
tc@box:~/pictures/P4$

--- End code ---

Juanito:
The problem was the missing files:

/usr/local/lib/ImageMagick-7.0.9/modules-Q16HDRI/coders/*la
/usr/local/lib/ImageMagick-7.0.9/modules-Q16HDRI/filters/*la

..presumably required by libltdl to load the convert libs

Refactored imagemagick/imagemagick-dev posted.
