Agus,

This is a shell escaping problem.  The single and double quotes have special
meaning to the various shells so you have to put a special "escape" character
in front of them.

eg. +lat_1=37d10\'41.058\"

This is out of the control of proj, and occures before proj gets the argument
input.

Best regards,
