Some of my major packages get this error and I wonder what causes it?
I am not interested in a solution for php, but a guideline to help me
fix any package with this problem.

The lines before the error should give some clues. The config.log it
mentions can be found in $PORT_TMPDIR/dev-lang/php-5.1.6/work in this
instance, that should give a more detailed error message.

This isn't necessarily a single problem for all the affected packages; the
configure script carries out a large number of tests, any one of which
could have failed.

Additionally, note that with some tests, any warnings (even if they are
harmless) can cause the test to fail.  A common example would be
unsupported CFLAGS -- CFLAGS that your currently configured version of GCC
doesn't recognize and so ignores, but spits a warning about.  Maybe you
setup your CFLAGS with a different version of GCC that recognized
different flags, or whatever you followed suggesting those CFLAGS was
based on a different GCC version.  Particularly if whatever they are
testing is only a gcc-warning as well, guess what, they usually fail on
any warning. As it happens, the Gentoo/amd64 arch team had enough problems
reported due to this that they instituted a filter in their profiles that
removes most flags the currently configured version of gcc doesn't
recognize, so the problem happens less frequently than it did, but the
unrecognized CFLAG warning isn't the only one gcc has by far, and if one
of the others pops up in a test, it could trigger a test failure and
ultimately a configure error as well.

In ordered to properly troubleshoot the general problem (a configure error
as reported in config.log), one really needs to know bash (well sh, which
on Gentoo is normally bash) scripting, since that's what the configure
script is written in.  The config.log file references line numbers in the
actual configure script, and if it's not immediately apparent from
config.log what the problem is, the next step is to open the configure
script to that line and figure out what it's doing, duplicating the
process by hand or adding echo debugs to the configure script where
necessary to see what's going on.  With a decent grasp of bash and at
least a vague idea of what all those tests in the configure script are all
about (note, knowing C/C++ is generally NOT necessary), one can usually
figure out what's going on and why, either correcting the problem (such as
CFLAGS that are choking the test in question) or bugging either with
Gentoo or very occasionally upstream, as appropriate.

Please do this ;)
If you still need help with the information in config.log give us the
relevant part of it.
The file is in somewhere /var/tmp/portage/php-5.1.6-r6/work/
