building amaya 9.99

[David Aubril <david.aubril%ac-nantes.fr@localhost>]

Hi everyone.
Being used to the amaya xhtml editor, I tried to build the last snapshot 
( which is not in pkgsrc yet ).
It stops with an error :
'checking for GTK+ - version >= 2.0.0... no
*** Could not run GTK+ test program, checking why...
*** The test program failed to compile or link. See the file config.log 
for the
*** exact error that occured. This usually means GTK+ is incorrectly 
installed.
configure: error:
The development files for GTK+ were not found. For GTK+ 2, please
ensure that pkg-config is in the path and that gtk+-2.0.pc is
installed. For GTK+ 1.2 please check that gtk-config is in the path,
and that the version is 1.2.3 or above. Also check that the
libraries returned by 'pkg-config gtk+-2.0 --libs' or 'gtk-config
--libs' are in the LD_LIBRARY_PATH or equivalent.'
Does someone know how to fix this ?
Best regards,
David ( trusiad )
