ARBHOME environment variable incorrectly set

[gawbul@…]

When using MacPorts to "install arb" the incorrect details are placed into the ~/.profile file.

The details should be:

ARBHOME=/opt/local/share/arb;export ARBHOME PATH=/opt/local/share/arb/bin:$PATH export PATH

however, the following information is added instead:

ARHOME=/opt/local/share/arb;export ARBHOME PATH=/opt/local/share/arb/bin:$PATH export PATH

note the spelling mistake of ARHOME!
