[ptx] Unable to compile libpano on Ubuntu 6.06

[Jp]

Hi,
I need to compile libpano on my Ubuntu 6.06 system.
Configuration phase is correct, no bug.
Make phase generates these errors :

/bin/sh ../libtool --tag=CC --mode=link gcc  -g -O2 -L..  -o PTmender  
PTmender.o -lpano12 -ljpeg -ltiff
gcc -g -O2 -o .libs/PTmender PTmender.o  -L/home/jp/libpano12-2.8.3 
/home/jp/libpano12-2.8.3/.libs/libpano12.so -lpng /usr/lib/libtiff.so 
/usr/lib/libjpeg.so -lz -lm -lc
PTmender.o: In function 
`main':/home/jp/libpano12-2.8.3/tools/PTmender.c:324: undefined 
reference to `InsertFileName'
:/home/jp/libpano12-2.8.3/tools/PTmender.c:261: undefined reference to 
`InsertFileName'
collect2: ld returned 1 exit status
make[2]: *** [PTmender] Erreur 1
make[2]: quittant le répertoire « /home/jp/libpano12-2.8.3/tools »
make[1]: *** [all-recursive] Erreur 1
make[1]: quittant le répertoire « /home/jp/libpano12-2.8.3 »
make: *** [all] Erreur 2

Apparently, the error concerns PTmender...
Could anyone help me ?

Thanks a lot.
