Problems compiling new version of libpano12

[Carlos E. G. Carvalho]

Hi people, I'm having dificulties on compiling a new version of
libpano12 to upgrade this port. Can anyone help me?

I have solved some initial problems and stopped on this one without
beeing able to go forward:

-----------------------
gcc -g -O2 -L.. -L../.libs -o panoinfo -lpano12
/usr/lib/crt1.o(.text+0x72): In function `_start':
: undefined reference to `main'
.../.libs/libpano12.so: undefined reference to `makePathToHost'
.../.libs/libpano12.so: undefined reference to `gtk_widget_grab_default'
.../.libs/libpano12.so: undefined reference to
`gtk_toggle_button_get_type'
(and many more "undefined reference" messages suppressed)
--------------------------------------------

I don't know where this "_start" function is. Before this problem there
was another one, due to libpano12.so not beeing found. To solve this I
added the "-L../.libs" to the gcc command line and got this problem
above.

Any hint?

I could maybe give access to my environment if someone is able to help
me.

Thanks,
