the file www-servers/apache/files/apache-2.2.16-prefix.patch is missing from the 20100930 snapshot and afaics from the repo at all. Reproducible: Always Actual Results: www-servers/apache-2.2.16 fails to build as of the missing patch. afaics the patch is for the config to adjust some paths for prefix. the files for 2.2.14-r1 and 2.2.15 are identical so i'll try to use them instead as a quick fix. anyway, the patch must be added...
yes, apache-2.2.15-prefix.patch did the job.
fixed, thx.
