Update converters/libetonyek to use devel/mdds1.2 ?

[Paul Goyette <paul%whooppee.com@localhost>]

Scanning through pkgsrc shows that converters/libetonyek is only 
package remaining that depends on the original devel/mdds package, while 
converters/orcus0.12, math/libixion, and misc/libreoffice all depend on 
the newer devel/mssd1.2 package.

WRT libreoffice, since it depends on libetonyek it indirectly depends on 
mdds as well as its direct dependency on mdds1.2 - therefore building 
libreoffice requires installation of _both_ versions of mdds!

It seems to me it should not be difficult to update libetonyek to depend 
on mdds1.2 and then we could retire the older mdds.

Thoughts?  Or is there some other reason to continue to maintain two 
versions of the mdds package?

FWIW, it appears that it's not quite as simple as just replacing the 
mdds/buildlink3.mk with mdds1.2/buildlink3.mk (in the Makefile), as this 
results in an error while building:

    checking for glm/glm.hpp... yes
    checking for MDDS... no
    configure: error: Package requirements (mdds-1.0) were not met:

    Package 'mdds-1.0', required by 'virtual:world', not found

    Consider adjusting the PKG_CONFIG_PATH environment variable if you
    installed software in a non-standard prefix.

    Alternatively, you may set the environment variables MDDS_CFLAGS
    and MDDS_LIBS to avoid the need to call pkg-config.
    See the pkg-config man page for more details.
