Howard,

regarding the EPSG 8.9 upgrade, it seems from 
https://github.com/OSGeo/proj.4/commit/b2d1648195d5a2e3ea07015a7a60ee7ee04337b9 
there was an issue with the regeneration of the proj 'epsg' file from the 
updated csv files pcs.csv, etc... with the new Kyrgyzstan SRS. 

For example there's the following line in 'epsg':
# Unknown
# Unable to translate coordinate system EPSG:7686 into PROJ.4 format.

But with GDAL updated:

$ gdalsrsinfo EPSG:7686

PROJ.4 : '+proj=longlat +ellps=GRS80 +no_defs '

OGC WKT :
GEOGCS["Kyrg-06",
    DATUM["Kyrgyzstan_Geodetic_Datum_2006",
        SPHEROID["GRS 1980",6378137,298.257222101,
            AUTHORITY["EPSG","7019"]],
        AUTHORITY["EPSG","1160"]],
    PRIMEM["Greenwich",0,
        AUTHORITY["EPSG","8901"]],
    UNIT["degree",0.0174532925199433,
        AUTHORITY["EPSG","9122"]],
    AUTHORITY["EPSG","7686"]]

So the definition in 'epsg' should be '+proj=longlat +ellps=GRS80 +no_defs '

I've actually manually run epsg_tr.py on gcs.csv and I do get the expected:
# Kyrg-06
<7686> +proj=longlat +ellps=GRS80 +no_defs  <>

So it seems that for some reason epsg_tr.py in your process found the 7686 
entry in gcs.csv but wasn't able to resolve it as WKT / ExportToProj4.


Same for

# Unknown
+# Unable to translate coordinate system EPSG:7692 into PROJ.4 format.

$ gdalsrsinfo EPSG:7692

PROJ.4 : '+proj=tmerc +lat_0=0 +lon_0=68.51666666666667 +k=1 +x_0=1300000 
+y_0=14743.5 +ellps=GRS80 +units=m +no_defs '

OGC WKT :

    GEOGCS["Kyrg-06",

Regarding the libgeotiff update, the updated pcs.csv, gcs.csv, etc... files have 
not been committed into SVN.
