The `ls -l` command shows "clang" in neither of the two paths.
I have now idea where the version of clang in /Developer/usr/bin came
from (I can't imagine other than from Apple). Nevertheless, when I copy
it to /usr/local/bin, where fink presumably can find it, I still get the
"C compiler cannot create executables" error.
I've used fink for years, and never had this problem. The only
connection I can think of is that I probably upgraded to Xcode 6.2 since
I had prexiously done a "fink update-all". (Apple says Xcode 6.4 is not
compatible with OS 10.9.5. That is, 6.2 is the most up-to-date version
for my OS.)
I am to infer from yor comments that clang is not a part of the Xcode
package?

Dear Mr. Hansen.
Responses to both your emails are here:
[summer:libidn-1.31-1/libidn-1.31]6 bobw% gcc --version

(dot 3)

The config.log file associated with libidn-1.31 gives the same complaint
about not finding clang:
[summer:libidn-1.31-1/libidn-1.31]4 bobw% more config.log
..
configure:4353: gcc -v >&5
clang: error: unable to find utility "clang", not a developer tool or in
PATH
But I notice an important point in that file:
There are several lines in that log-file beginning "PATH:" , but none of
which contain the path to the `clang` executable -- namely
/Developer/usr/bin -- as I see with:
There is no /Developer on 10.9/Xcode 6.2. Any clang there is not part
of Apple's default build tools setup. Apple's clang lives in
/usr/bin/clang, which is a stub for
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang.
[summer:libidn-1.31-1/libidn-1.31]7 bobw% echo $path
/Users/bobw /Developer/usr/bin /usr/local/bin /usr/X11R6/bin /sw/bin
/Applications /Applications/mol_structure/VMD
/Applications/mol_structure/VMD/NAMD_2.7b1_MacOSX-x86
/Applications/android-sdk/android-sdk-mac_x86/platform-tools /sw/bin
/sw/sbin /bin /sbin /usr/bin /usr/sbin
/usr/local/teTeX/bin/i386-apple-darwin-current /usr/local/bin
/usr/X11R6/bin
That apparently accounts for the error. But leavea me with further
questions: Why is the path seen by fink different than that seen by the
shell? And how do I set the former?
Fink on purpose is designed to ignore as much as it can of a user's
local setup, especially things like PATH and other ENVVARS. However,
it can't deal with actual changes to the filesystem.
What is the output of (this is a one line command):
ls -l
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
/usr/bin/clang
and
/usr/bin/clang --version
