ImageMagick on MacOS 10.10 Yosemite - dyld错误

I get the following error when trying to set the path to the imagemagick binary in Drupal (7.31):

dyld: Library not loaded: /usr/local/lib/liblcms2.2.dylib
Referenced from: /usr/local/bin/convert
Reason: no suitable image found.  Did find:
/usr/local/lib/liblcms2.2.dylib: stat() failed with errno=13
/usr/local/lib/liblcms2.2.dylib: stat() failed with errno=13

I've tried unlinking, reinstalling and relinking but to no avail. Also installed php55 using brew and added imagick via pecl but no joy.

The convert binary works fine on the command line, so could be a php config error, but I can't seem to find a solution.

Permissions on the referenced file are lrwxr-xr-x. ls -al gives:

lrwxr-xr-x 1 <username> wheel 46B 21 Oct 19:15 /usr/local/lib/liblcms2.2.dylib -> ../Cellar/little-cms2/2.6/lib/liblcms2.2.dylib

Help?
