The @MKCONF@ file seems to not include autoswc.mk. This means that

You have used a non-standard cache name. To let configure scripts

find it, you should add the following line somewhere in your

@MKCONF@ file, in case it is not there yet:

AUTOSWC_CACHE_NAME= ${cachename}

|
|
Please remember that by using a system wide cache file, you assume
|
|
that the results stored in it may get outdated and cause strange build
|
|
failures in third-party packages. When reporting bugs, be absolutely
|
|
sure it is not your fault. Check the autoswc(8) manpage for more
|
|
details.
