Hum, urpmi use rpm dependencies, which use effectively so name, so name should
be changed if compatibility is broken.
$ rpm -qR xalan-c | grep libstdc
libstdc++-libc6.2-2.so.3
$ ldd /usr/bin/testXPath | grep libstdc
libstdc++-libc6.2-2.so.3 => /usr/lib/libstdc++-libc6.2-2.so.3 (0x4083d000)
$ objdump -x /usr/lib/libstdc++-libc6.2-2.so.3 | grep SONAME
SONAME libstdc++-libc6.2-2.so.3
How can we known more here ?
