The second error is more weird. After using your commands (sudo
port clean pango; sudo port -d install pango 2>&1 | tee ~/Desktop/
pango.txt; bzip2 ~/Desktop/pango.txt ), it went through, but it
was not able to activate. It should automatically desactivate the
old and install the new one, no?
No, since you used "install". If you had used "upgrade" instead,
it would have done so. So now you should:
Is this actually true, or is it a typo, a slip of mind? The answer
might be interesting. Because it is actually the opposite: I used
upgrade, and you told me to use install. What is in fact the
difference between install of an existing port, or upgrading it?
Maybe install uses the existing ports on which it depends, while
upgrade tries to upgrade the dependencies as well?
"install" installs a port. If another version of that port is already
installed, then you get the error you showed.
"upgrade" upgrades a port and, if necessary, its dependencies first.
Another version of that port must already be installed, and it will
be deactivated before the new version is activated.
I told you to use "install" because I did not know you already had
another version of pango installed. Since you did, it would have been
more straightforward to use "upgrade" in your case.
