That the -dev package is missing a Depends on the library is a bug for
sure.  But I'm not sure about the rest, and the validity of the patch.  

First of all, TTBOMK there's no significant difference between kpathsea
sources in tetex-bin (etch) and texlive-bin, and we didn't patch
anything related to -fPIC in tetex-bin, nor use compiler flags. 

Second, the build log stops with:;

***********************
cc -shared .libs/libevince_properties_page_la-ev-properties-main.o \
-Wl,--whole-archive \
[...]
 -lm -lkpathsea -pthread \
-Wl,--export-dynamic -pthread -pthread -Wl,-soname \
-Wl,libevince-properties-page.so -o .libs/libevince-properties-page.so
/usr/bin/ld: /usr/lib/libkpathsea.a(tex-file.o): relocation R_X86_64_32S \
against `kpse_format_info' can not be used when making a shared object; \
recompile with -fPIC
/usr/lib/libkpathsea.a: could not read symbols: Bad value
***********************

Why does ld try to use libkpathsea.a for dynamic linking?  Isn't that
the real bug?  Or ist that a fallback if the so symlink points to
nothing? 

Finally, I don't think your patch will achieve anything:

+CXXFLAGS += -fPIC
+export CXXFLAGS

because libkpathsea is not written in C++.  Or will gcc used as C
compiler honour CXXFLAGS?
