It's fine to use this when installing the Perl modules ...

... the problem must have happened at an earlier stage, when installing the CWB binary distribution (with cqp, cwb-encode, etc.).  When you did this, you must have edited "install-cwb.sh" to set a different installation path, like so:

	## Directory tree where the CWB will be installed
	## (e.g. /usr/local installs CQP in /usr/local/bin, manpages in /usr/local/share/man, etc.) 
	PREFIX='~/Installs/CWB'

(I don't remember the exact path you used).  The problem is that "~" isn't always interpreted correctly to mean your home directory.  It works in the install script, but not e.g. in the CWB/Perl modules.

The cleanest solution is to always specify the complete absolute path, e.g.

	PREFIX='/Users/my_name/Installs/CWB'

At least on my Mac, it also seems to work well if I just omit the quotes:

	PREFIX=~/Installs/CWB

You just have to be careful about blanks or other special characters in the directory names, but this should be avoided anyway.

Hope this finally solves your CWB/Perl woes!

Best wishes,
Stefan
