CMake log needed to help find a bug

[Ian Wadham]

I reported a problem with kdelibs4 @4.8.2_0 failing to detect compiler characteristics
correctly, see https://trac.macports.org/ticket/34605?replyto=1#comment and also
https://bugs.kde.org/show_bug.cgi?id=300429

A KDE developer has responded to the latter report and he has asked for logs of
CMake output from my Macports build of kdelibs4 @4.8.2_0.  How do I get this?

AFAICS the Macports logs are deleted after a successful build.  So must I do:

    sudo port uninstall  kdelibs4 @4.8.2_0
    sudo port -k install  kdelibs4 @4.8.2_0

...?  And if I do, how do I find the logs?  And how do I find the logs I want amongst
all the other logs?

Thanks in advance, Ian W.
