if they should all be in `$SAGE_LOCAL/lib`, then I have
{{{
liblapack.a
libgsl.a
libgsl.dylib
libgsl.la
libgslcblas.a
libgslcblas.dylib
libgslcblas.la
libblas.a
}}}
sure, I have the same.
> Maybe that helps. Where does libcblas come from in other systems? It's
not a Sage package, and the BLAS spkg-install only installs libblas.a, as
far as I can tell.
On my machine I have, surely coming from Xcode (part of Accelerate
framework, formerly altVec...):
{{{
$ ls -l /usr/lib/*cblas*
lrwxr-xr-x 1 root wheel 112 Apr 12 1976 /usr/lib/libcblas.dylib ->

$ ls -l /usr/lib/*atlas*
lrwxr-xr-x 1 root wheel 112 Apr 12 1976 /usr/lib/libatlas.dylib ->

lrwxr-xr-x 1 root wheel 114 Apr 12 1976 /usr/lib/libf77lapack.dylib ->

}}}
These are platform-optimised libraries, that should be used on MacOSX.
So your linker trouble seems to be a sign of Xcode not being properly
installed, or that your Xcode is much older than mine, and the directories
layout has changed.
Do you have anything like this in /usr/lib ?
But anyway, one just have to link against the native libraries.
What does your gcc -v say? In my case:
{{{
$ gcc -v
Using built-in specs.
Target: powerpc-apple-darwin9
Configured with: /var/tmp/gcc_42/gcc_42-5577~1/src/configure --disable-
checking --prefix=/usr --mandir=/usr/share/man --enable-
languages=c,objc,c++,obj-c++ --program-transform-
name=/^[cg][^.-]*$/s/$/-4.2/ --with-slibdir=/usr/lib --build=i686-apple-
darwin9 --with-gxx-include-dir=/usr/include/c++/4.0.0 --program-prefix=
--host=powerpc-apple-darwin9 --target=powerpc-apple-darwin9
Thread model: posix
gcc version 4.2.1 (Apple Inc. build 5577)
}}}
So you see with-slibdir=/usr/lib there, so this must mean that it picks up
these libcblas, etc, there.
