Checked with the previous info file, which should be functionally  
equivalent.
First, to get things basically straight, I added to the patchscript  
the line

sed -i'' -e '\XL/usr/libXd' SConstruct

to get rid of that wrong  -L/usr/lib  flag
[was trivial to find : a grep showed it was the only occurrence of / 
usr/lib
in the builddir, and it was in a conditional on macosx (additional  
reason to be wrong ...)]

Added also the required paths (for freetype, fontconfig, etc _ no  
attempt at minimality ..)
  to CFLAGS, and set  CXXFLAGS in the same way to be sure;  +  same  
for LDFLAGS
(cf next point about  -H _ DON'T put that in an official info file ..):

The build went perfectly _ no libiconv issues or whatever _ , and now  
linked to fink's pkgs; thus :
deps now, according to otool :

> # otool_deps linuxdcpp
> atk1-shlibs, bzip2-shlibs, cairo-shlibs, fontconfig2-shlibs,

> libglade2-shlibs, libiconv, libxml2-shlibs, pango1-xft2-ft219- 
> shlibs, xorg-shlibs

and hence also the corresponding bdeps

Finally, to check whether no include files from other pkgs were  
(indirectly) included
(there were -I flags for such pkgs, like  -I/sw/include/pixman-1), I  
used the log file
(was created by "fink -ky rebuild linuxdcpp 2>&1|tee /sw/var/logs/ 
linuxdcpp.log"),
to get the list of all pkgs (except x11) from which headers were used :

> # egrep '^\.+ /' /sw/var/logs/linuxdcpp.log|sort -u|sed -r -e 's,^\.

> xft2-ft219-dev

So indeed nothing else...
