Thanks, the relevant lines are:

configure:18782: cc -o conftest -I/usr/local/include -fvisibility=hidden 
  -Wl,-rpath,/usr/local/ssl-1.1.1/lib -L/usr/local/ssl-1.1.1/lib 
-L/usr/local/lib conftest.c -lcrypto  -lrt -lm -ldl -lnsl -lgpg-error 
-lsystemd-daemon -lxml2 -lz -lm -ldl >&5
configure:18782: $? = 0
configure:18791: result: yes
configure:18934: checking for SSL_CTX_set_ssl_version in -lssl
configure:18959: cc -o conftest -I/usr/local/include -fvisibility=hidden 
  -Wl,-rpath,/usr/local/ssl-1.1.1/lib -L/usr/local/ssl-1.1.1/lib 
-L/usr/local/lib conftest.c -lssl  -lcrypto -lrt -lm -ldl -lnsl 
-lgpg-error -lsystemd-daemon -lxml2 -lz -lm -ldl -lcrypto >&5
/bin/ld: /usr/local/ssl-1.1.1/lib/libcrypto.a(threads_pthread.o): 
undefined reference to symbol 'pthread_rwlock_wrlock@@GLIBC_2.2.5'
/bin/ld: note: 'pthread_rwlock_wrlock@@GLIBC_2.2.5' is defined in DSO 
/lib64/libpthread.so.0 so try adding it to the linker command line
/lib64/libpthread.so.0: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
configure:18959: $? = 1
configure: failed program was:

So although "-pthread" is part of OPENSSL_LIBS, it doesn't get used 
during configure (which uses hard-coded 'LIBS=" -lssl -lcrypto 
`$PKG_CONFIG --libs openssl`   $LIBS"' in this check). So a checken or 
egg problem.

Could you do yet another test? First manipulate the configure script 
with the following two commands:

cp -p configure configure.saved

# the following is one long line

sed -e 's#PKG_CONFIG --libs openssl#PKG_CONFIG --libs --static 
openssl#g' configure.saved > configure


and then redo the whole build including running configure. If that works 
fine, it might be possible to add a configure flag for static OpenSSL 
linking.

Thanks and regards,

Rainer
