Installing KCachegrind in order to profile output from ruby-prof turned out to be quite a time consuming task.
This was all performed on an iMac with a 2.16 GHz Intel Core 2 Duo CPU and 4GB 667 MHz DDR2 SDRAM.
The initial command:
sudo port install kcachegrind
ran for several hours only to fail with :
checking for XPROTO... configure: error: Package requirements (xproto >= 7.0.13) were not met: Requested 'xproto >= 7.0.13' but version of Xproto is 7.0.11
I manually installed the correct version of xorg-xproto:
sudo port deactivate xorg-xproto # deactivates version 7.0.11_1 sudo port install xorg-xproto # installs version 7.0.14_1
Restarted the KCachegrind install:
sudo port install kcachegrind
Then waited again.
The next error encountered:
---> Activating xorg-renderproto @0.9.3_0 Error: Target org.macports.activate returned: Image error: /opt/local/include/X11/extensions/render.h is being used by the active render port. Please deactivate this port first, or use the -f flag to force the activation.
I did what the error message suggested:
sudo port -f activate xorg-renderproto
It looks as though some other install had installed files
/opt/local/include/X11/extensions/render.h /opt/local/include/X11/extensions/renderproto.h
the install process copied the old files to a tmp directory. A quick diff of the files showed that the installed files were the newer files.
Restarted the install of kcachegrind:
sudo port install kcachegrind
The install continued for several more hours. kdelibs3 taking 2 hours.
When everything was finally installed I do have a working version of kcachegrind running.
In total the install ran for approximately 8 hours.
