Yes, that's a restriction of glibc and static linking, google it.

Congrats! You did it!

Perhaps you can build these statically yourself (as was recommended for
all the other dependant stuff).

If both static and dynamic libraries are found, the linkers will by
default prefer the dynamic one.
Choices can be manipulated, but no build system I know of supports
this, because it would make ./configure and the Makefiles too
What comes to mind:
a) Build a fake chroot build environment, where you hide all the
b) At least GNU ld allows you to specify the preference per library on
the command line. From the build, you take the linker command line
(which you observe with "make V=1"). Replace stuff like this:
Or, you can also add stuff before each and every explicitly specified lib:
$ gcc -o something [...] -Wl,-Bdynamic -ltiff -Wl,-Bstatic -lpng [...]
You can also do this in blocks: after "-Wl,-Bdynamic", list all the one
you want dynamically, then add "-Wl,-Bstatic" and list all the ones you
