Bug#946068: lv2dynparam1 FTCBFS: lv2core.pc not found

[Helmut Grohne]

Source: lv2dynparam1
Version: 2-6
Severity: serious
Tags: ftbfs

lv2dynparam1 fails to build from source in unstable, because it fails
finding lv2core.pc using pkg-config:

| checking for LV2... no
| configure: error: Package requirements (lv2core >= 1) were not met:
| 
| No package 'lv2core' 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 LV2_CFLAGS
| and LV2_LIBS to avoid the need to call pkg-config.
| See the pkg-config man page for more details.
|  tail -v -n \+0 config.log
