OK, I did some digging into the matter and this is what I found - I started
with XRenderFindDisplay unresolved name.

On Mandriva, where my tool worked OK without any additional efforts,
Xrender library is in /usr/X11R6/lib/libXrender.so file, and this file/library
defines XRenderFindDisplay symbol:

"
[13] 23:32 sergei comp home net:/ibm/home/sergei> nm -A -C -D /usr/X11R6/lib/libXrender.so | grep
XRenderFindDisplay
/usr/X11R6/lib/libXrender.so:00001670 T XRenderFindDisplay
[14] 1:01 sergei comp home net:/ibm/home/sergei>
".

On MEPIS/Ubuntu there are (at least) two files with libXrender basename:

1) /usr/X11R6/lib/libXrender.a :

"
mepis1:/mnt/hdd2/sergei> nm -D -A -C /usr/X11R6/lib/libXrender.a
nm: Xrender.o: No symbols
mepis1:/mnt/hdd2/sergei>
";

2) /usr/lib/libXrender.so :

"
mepis1:/mnt/hdd2/sergei> nm -D -A -C /usr/lib/libXrender.so | grep XRenderFindDisplay
/usr/lib/libXrender.so:00005a97 T XRenderFindDisplay
mepis1:/mnt/hdd2/sergei>  
".

So, the second file has the needed resolution.

I added pre_make_sub for 'pango' target which replaces in every Makefile

X_LIBS =  -L/usr/X11R6/lib -lX11

with

X_LIBS = -L/usr/lib -L/usr/X11R6/lib -lX11
.

Please pay attention that '-L/usr/lib' comes before '-L/usr/X11R6/lib' -
otherwise it doesn't work - I'm not quite sure why.

So, my main question:

is it a flaw in 'configure' of 'pango' or in directory structure and
library organization of MEPIS/Ubuntu ?

Thanks,
  Sergei.
