Well, to be fair, rpmbuild isn't to blame here. The spec file probably
has something like:
%configure --with-foo --with-bar
That simply invokes configure with a set of sane options (including
pointing to the system library/binary paths). For example, on my rawhide
x86_64 system, %configure evaluates to:
CFLAGS="${CFLAGS:--O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2
-fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64
-mtune=generic}" ; export CFLAGS ;
CXXFLAGS="${CXXFLAGS:--O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2
-fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64
-mtune=generic}" ; export CXXFLAGS ;
FFLAGS="${FFLAGS:--O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2
-fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64
-mtune=generic -I/usr/lib64/gfortran/modules}" ; export FFLAGS ;
./configure --build=x86_64-unknown-linux-gnu
--host=x86_64-unknown-linux-gnu \
--target=x86_64-redhat-linux-gnu \
--program-prefix= \
--prefix=/usr \
--exec-prefix=/usr \
--bindir=/usr/bin \
--sbindir=/usr/sbin \
--sysconfdir=/etc \
--datadir=/usr/share \
--includedir=/usr/include \
--libdir=/usr/lib64 \
--libexecdir=/usr/libexec \
--localstatedir=/var \
--sharedstatedir=/var/lib \
--mandir=/usr/share/man \
--infodir=/usr/share/info
Now, if your spec file used "./configure" instead of "%configure", you
could hardcode any of those paths into the spec that you want. It
wouldn't be portable though. Even if that package built, it would still
depend on things not packaged up, and complain on installation.
As a possible alternative, if you can make packages for the unstable
library dependencies, then you can build this package in a chroot where
the unstable libraries are installed. Or, if the libraries have unique
sonames, you should be able to have them both installed in system
locations and eliminate the need for the chroot.
