On Linux I get this output in config log: configure:41995: checking for xdrmem_create in -lportablexdr configure:42030: gcc -o conftest -g -O2 conftest.c -lportablexdr >&5 /usr/bin/ld: cannot find -lportablexdr collect2: ld returned 1 exit status [...] configure:42069: checking for library containing xdrmem_create configure:42110: gcc -o conftest -g -O2 conftest.c >&5 configure:42117: $? = 0 configure:42148: result: none required The first explicit check for libportablexdr fails, but the second test succeeds and finds xdrmem_create from glibc.
